Abstract
Organophosphorus compounds play several essential roles in organic chemistry, such as valuable ligands in transition metal catalysis and functional materials. We have developed versatile organophosphine syntheses via Pd-catalyzed P-C cross-coupling reactions in the course of our study using silylphosphines. Up to three aryl groups can be selectively incorporated into the same phosphorus atom in a stepwise manner. In addition, we found the formation of phosphorus-ylide containing phosphacycles, λ5-phosphinines, during the extension of silylphosphine chemistry.
