In this paper Maravanji S. Balakrishna and colleagues from India and the USA report the first examples of cyclodiphosphazane-derived phosphine ligands and their transition metal chemistry. The chemistry of cyclodiphosphazanes has received considerable interest recently due to their utility as ligands towards both main group and transition elements, building blocks in macrocyclic chemistry, mechanistic probes for organic reactions, and catalytic and biological applications.  Find out more in this Dalton Transactions ‘Hot Article’.

Computational studies have made an important contribution to understanding the mechanisms of C-H bond activation by transition metal systems.  In this Hot Article David Davies and Stuart A. Macgregor from the University of Leicester and Amalia Poblador-Bahamonde from Heriot-Watt University have used density functional theory calculations to define the energetics of ethene hydroarylation with a [Ir(κ²-OAc)(PMe₃)Cp]⁺ catalyst and to assess possible competing side reactions.
