The cover of this week’s OBC features work from Min Shi et al. at Shanghai Institute of Organic Chemistry and 
Texas Tech University, who have used chiral zinc(II)–imidazoline–phosphine complexes in a novel catalytic system for the asymmetric Mannich-type difluorination of hydrazones with difluoroenoxysilanes.

Resnati and colleagues have conducted an NMR study of phosphate oxoanion binding of a 2-iodo-imidazolium receptor with charge assisted halogen bonding, finding a surprisingly strong binding constant for phosphate anions, their work is highlighted on the outside front cover.
On a completely different topic, Anderson and Moreno have been using CO2 to produce ureas at ambient conditions, using 12- and 14- electron titanium imido complexes:
On the outside front cover of this week’s issue is a 
The inside front cover is work from Jonathan Guimond-Tremblay, Université Laval, et al. on the synthesis of three monofluorinated dimyristoylphosphatidylcholine derivatives for use as probes in 19F NMR studies to study the effects of drugs and peptides on model membranes.
On the outside front cover a communication from Chi-Ming Che and Man-Kin Wong et al. is highlighted, showing their method for gold-mediated bifunctional modification of oligosaccharides via a three-component coupling reaction.
On the inside front cover is an article from Brindaban C. Ranu et al. on copper catalysed cyanation of styrenyl bromides to give functionalized cinnamonitriles with preserved stereochemistry.
