Preparation of NHC-substituted phosphitepalladacycles

The preparation of unsaturated NHC-substituted phosphitepalladacycles via phosphitepalladacycle acetato and chloro precursors and azolium salts with non-coordinating anions in DMSO is reported. With this one-pot synthesis NHC-substituted phosphitepalladacycles are obtained avoiding multi-step reactions. The molecular structures of an acetate-bridged phosphitepalladacycle dimer, an unsaturated NHC-substituted palladacyclic complex and one acetylacetonato phosphapalladacycle complex have been determined by single-crystal X-ray analysis.
