Expanding the Utility of Expanded NHCs

In their recent paper in Dalton Transactions, Stasch, Jones and co-workers describe the use of bulky ring-expanded N-heterocyclic carbenes (NHCs) for the stabilisation of Group 15 trichlorides, ECl3; E = P, As, Sb.

The authors show that mixing 1:1 solutions of the ring-expanded, 2,6-diisopropylphenyl-subsitutied NHC “6-Dipp” with ECl3 (E = P, As, and Sb) affords satisfactory yields of the corresponding [(6-Dipp)ECl3] adduct, noting that the use of the alternatively-substituted mesityl-substituted carbene (6-Mes) led to a mixture of products thus highlighting the importance of the 6-Dipp ligand for stabilising the adducts.

Adduct formation

The group characterised each adduct using standard means, including NMR spectroscopy and electron-impact (EI) mass spectrometry. In the cases of P and Sb, they were able to use X-ray crystallography to determine the solid state structures of those compounds and observed that each pnictogen centre adopted a saw-horse geometry.

When the researchers tried to reduce these adducts using either KC8 or a Mg(I) derivative, they were mostly unsuccessful, however they were able to reduce [(6-Dipp)PCl3] using the former reagent to form a unique dicationic carbene-stabilized P4 unit. Once again, the authors attributed the stability of this species to the steric profile of the 6-Dipp ligand framework. The X-ray crystal structure of the complex shows a P4-butterfly geometry stabilised by two carbene moieties.

P4 compound

During the course of their reactivity studies, the group identified (6-MesH)2 as a byproduct resulting from reaction of in-situ generated [(6-Mes)PCl3] with KC8. With further optimisation, they revealed that this moiety could be accessed from treatment of [6-MesH]Br with KC8 – marking the first successful reductive coupling of cyclic amidinium ions. Along with NMR and X-ray crystal data, a cyclic voltammetry (CV) study was also performed on (6-MesH)2 to fully characterise this unique species.

The successful syntheses of all these p-block NHC complexes pave the way for new discoveries in fundamental reactivity, bonding, and catalysis employing main group elements, further demonstrating the potential of these elements to perform exciting chemistry.

Breaking zirconacycles is hard to do

In their recent paper in Dalton Transactions, Erker and co-workers describe B(C6F5)3 as an unorthodox probe for the detection of σ ligand character and allenoid-type bonding in substituted zirconocenes.

Chemists have studied the strong Lewis acid, B(C6F5)3 for the past decade, particularly for its uses in frustrated Lewis pairs (FLPs). This small molecule has, however, gained popularity in other areas of chemistry. In catalysis, B(C6F5)3 is commonly employed to generate cationic metal centres by alkyl group abstraction (σ-ligand abstraction) to activate molecular pre-catalysts for use in polymerisation.

Zirconocene cleavage

Expanding the scope beyond alkyl groups, Erker and co-workers showed that B(C6F5)3 can mediate cleavage of Zr-C(sp3) bonds in zirconacycles, creating unique allene coordination complexes. In one instance, they used an unsubstituted zirconacycloallenoid (Zr-CH2-) to synthesise a zwitterionic (η2-allenyl)zirconocene with an allene bond angle close to linearity.

In a second case, they reacted a 4-phenyl substituted zirconacycloallenoid (Zr-CHPh-) to produce a zwitterionic allene-coordinated zirconocene.

In demonstrating such reactivity, the authors lead the way for B(C6F5)3 to act as a standard probe for detecting latent σ ligand character in other molecules.

Hang on to your carbene

What we think of as “organic chemistry” doesn’t often focus on the structure and bonding environments of the carbon atom, unlike inorganic chemistry which often does so with heteroatoms.  So I don’t think I’m going far out on a limb when I say that perhaps the key development in the structure and bonding of carbon over the last quarter century has been the isolation and use of the persistent carbene. 

Arduengo carbene

Arduengo carbene

A carbene is a divalent carbon atom possessing two electrons.  Once thought to be unisolable, its history is recent enough that almost all important figures in its development are not only still living to this day, but still working.  Ron Breslow proposed that carbenes could be isolated in 1957, Guy Bertrand isolated a liquid dicarbene in 1989 and, in 1991, Anthony Arduengo reported the first comprehensive solid-state data of the type of carbene that now bears his name (pictured above).  

So why waste the words of a short post blog on historical perspective?

Because the uses of the carbene have fallen almost entirely in one direction.  Primarily, the carbene has been used as a strong s 2-electron donor – attached to many transition metal atoms it forms very stable complexes, and it is relatively easy to vary its size. 

Only recently have the uses of the carbene diverged. 

In a recent Dalton Transactions paper, Arnold, Love and co-workers present work on labile carbenes tethered to rare earth metals by an alkoxy arm.  On rare earth metals – which are much harder Lewis acids than late transition metals – the soft carbene donor and hard metal acceptor are poorer matches.  Thus the carbon-metal bond may break, freeing the carbene for reactivity, while the hard alkoxy arm keeps the ligand tethered to the metal.

carbene reactivity

Reactivity of tethered alkoxycarbene complexes 

The authors present some examples of reactivity, including co-operative activation of pyrroles and alkynes by the carbene and metal centres, as well as outer-sphere interactions in the form of hydrogen bonding between pyrroles and the metal-bound O atom in solution.   Despite these being small steps, they are nonetheless important if the carbene is to find new roles outside stabilising late transition metal centres.

Enzyme-Inspiration for a New Nanoswitch

Enzymes function as biological catalysts in a wide array of reactions which are essential for sustaining life. They are almost always large protein molecules which adopt complex three dimensional structures, yet are able to remain structurally dynamic in order to allow the function of the enzyme to be switched on and off.

This feature allows an enzyme’s catalytic activity to be active only when required in the metabolic pathway in which it is involved. For this reason, enzymes have long been a source of inspiration to researchers involved in the design and synthesis of artificial molecular switches and machines.

SARS-CoV 3CLpro is a protease enzyme which is involved in the replication and transcription process of the human coronavirus, the virus which causes severe acute respiratory syndrome (SARS). This enzyme is catalytically inactive as a monomer and only functions as a catalyst when it is bound with another monomer in a complex called a homodimer.

Both crystallographic and mutation studies have implicated several amino acid residues in the dimerization process, however the exact mechanism of dimer formation and how this activates the enzyme’s catalytic activity is still unconfirmed.

 Nanoswitch mechanism 

 Scheme 1. Switching between open and close conformations of nanoswitch 1 in response to metal ion addition

Drawing inspiration from this monomer-dimer on-off mechanism, Schmittel and co-workers have devised a molecular switch capable of toggling between monomeric and dimeric forms in response to the addition of different metal ions. With no metal ions present, the triangular framework adopts the ‘OPEN-I’ conformation (Scheme 1). Upon the addition of copper(I) ions, the two pyridine-based ligands come into proximity to mutually coordinate the metal.

This changes the conformation of the framework to the ‘CLOSE’ state. Addition of iron(II) ions to the ‘CLOSE’ state again changes the molecular conformation, as the iron(II) ions occupy the terpyridine moiety and the copper(I) ions move to occupy only the shielded phenanthroline ligand.

This both forms a homoleptic dimer, as the iron(II) ions can coordinate two terpyridine moieties simultaneously from two different molecules, and creates a coordinatively unsaturated copper species which acts as a catalyst for a cyclopropanation reaction. The authors impressively demonstrate the reversibility of each step, with the removal of metal ions changing the framework back to its uncoordinated conformation.

In this way, they have successfully made a molecular switch which responds to a metal ion signal (Fe2+) and turns a catalytic complex on and off. Like SARS-CoV 3CLpro enzyme, the catalytically active state is the homodimer, with the monomeric form being catalytically inactive.

Salt lakes worth their lithium

Researchers in Japan have demonstrated the exceptional potential of a hydrated titanium oxide to extract lithium from salt lake brine collected from Salar de Uyuni in Bolivia, the world’s largest salt flat.
