Abstract
Pt to a T! Treating bulky N-heterocyclic carbene (NHC) ligands with [PtMe3I]4 results in rapid elimination of ethene and formation of [PtMeI(NHC)2] complexes. These complexes are suitable materials for the synthesis of T-shaped platinum(II) complexes stabilised by agostic interactions. X-ray structure determination of one of these complexes shows a rather long ζ agostic interaction (see figure).
