Arene displacement, C–H activation and acetonitrile insertion reactions enabled by coordination of a functionalized iminophosphorane to a Ru^II–p-cymene scaffold

Abstract

Reaction of sterically demanding iminophosphorano-phosphine, Ph2PCH2Ph2P=NAr* (here onwards referred to as PCPNAr*; Ar* = 2,6-dibenzhydryl-4-methylphenyl) (1) with [Ru(η6-p-cymene)Cl2]2 yielded three different types of complexes, [RuCl2{(η6-p-cymene)(PCPNAr*)-κ1-P}] (2), [RuCl{(P(O)CPNAr*)(κ2-N,C)(C-η6-arene)}] (3) and [RuCl{(POCP=NAr*)(κ2-N,C-o)(C-η6-arene)}]...
