✦ Synopsis

Abstract

The cover picture shows one of donor‐stabilized phosphenium compounds which have been obtained by direct addition of chlorophosphanes to the 1,3‐dimethylimidazolium‐2‐carboxylate without any further purification step. Their stronger κ‐acceptor character similar to phosphites and their ionic nature render these ligands very promising in the development of new continuous‐flow catalytic processes. Details of phosphorylation mechanisms of imidazolium‐2‐carboxylate as well as the electronic and steric properties of these adducts are discussed in the article by J. Andrieu et al. on p. 4877 ff.
