P, N-Heterodifunctional ligands by selective Staüdinger reaction of β-substituted vinylazides with ( Z)-1,2-bis(diphenylphosphanyl)ethene and formation of cyclometalled complexes of palladium(II) of these ligands — crystal and molecular structure of a new chiral cyclometallaphosphoraniminophosphane of palladium(II)

Staüdinger reactions of the β-aryl-, heteroaryl- and ferrocenylvinylazides ( 2) with ( Z)-1,2-bis(diphenylphosphanyl)ethene afford the P, N-ligands ( 3) in good yields. Reaction of 3 with dichlorobis(benzonitrile)palladium(II) leads to the Pd(II) metallacycle derivatives 5. The molecular structure o...

Description
Summary:Staüdinger reactions of the β-aryl-, heteroaryl- and ferrocenylvinylazides ( 2) with ( Z)-1,2-bis(diphenylphosphanyl)ethene afford the P, N-ligands ( 3) in good yields. Reaction of 3 with dichlorobis(benzonitrile)palladium(II) leads to the Pd(II) metallacycle derivatives 5. The molecular structure of 5e has been determined by X-ray crystallography. The electrochemical behavior of this compound is also reported.
