Facile synthesis of [(NHC)(NHCewg)RuCl2(CHPh)] complexes

The utility of [(NHC)(PPh3)RuCl2(CHPh)] for the facile and efficient synthesis of ten complexes of the type [(NHC)(NHCewg)RuCl2(CHR)] with saturated and unsaturated NHC ligands in 85–94% isolated yield via a simple one step synthesis utilizing [AgI(NHCewg)] as NHCewg transfer reagents was demonstrated.

A facilitated synthesis of (NHC)(NHCewg)RuCl2(CHPh) complexes is reported – which does not rely on PCy3 or PCy3 containing intermediates. Figure optionsDownload as PowerPoint slide
