Abstract:
Sterically protected organophosphorus compounds are described, involving diphosphenes, phosphaethenes, diphosphinidenecyclobutenes (DPCBs), phosphaalkynes, phosphaquinones, diphosphathienoquinones, and so on of coordination number 2 or 1. Application of the DPCBs as well as phosphinophosphaethenes as a ligand of transition-metal catalysts for several organic coupling reactions has been investigated.
Keywords: coupling reactions; diphosphathienoquinones; diphosphenes; diphosphinidenecyclobutenes; Organophosphorus; phosphaalkynes; phosphaethenes; phosphaquinones; transition-metal catalysts.
