摘要：

A high degree of diastereoselectivity was achieved in the coordination of monodentate phosphine PMeBu(t)Ph with dimeric chloro-bridged ortho-palladated complexes in solution due to the modification of the stereoselector structure, namely by the creation of asymmetry in the environment of nitrogen donor atom and by the fitting of substituents sizes in the palladacycle. The stereochemistry of complexation is discussed in the terms of equilibrium constants between two diastereomers of monophosphine complexes estimated from the P-31 NMR data.
