摘要

A palladium–iminophosphine complex was demonstrated to be an efficient catalyst for the homocoupling of organostannanes. Allyl acetate works effectively as an oxidant in the reaction of alkynylstannanes to give conjugated diynes, whereas biaryls and dienes are readily obtained through the homocoupling of aryl- and alkenylstannanes in an open air. ... Ligands often play important roles in transition metal catalysis. We disclosed that a palladium complex coordinated by an ...
