ZEROVALENT PALLADIUM AND PLATINUM COMPLEXES OF AMINOMETHYLPHOSPHINES - CRYSTAL STRUCTURE OF THE PALLADIUM(0) DIBENZYLIDENEACETONE COMPLEX [PD(PHCH=CHCOCH=CHPH)(((C6H11)(2)PCH2)(2)NME)]

摘要

Tris(dibenzylideneacetone)dipalladium and bis(dibenzylideneacetone)platinum re act with N, N-bis(dicyclohexylphosphinomethyl)methylamine, (Cy(2)PCH(2))(2)NMe (Cy = cyclohexyl), and with N, N-bis(diphenylphosphinomethyl)methylamine, (Ph(2)PCH(2))(2)NMe (Ph = phenyl), to give the complexes [M(dba){(R(2)PCH(2))(2)NMe}] (M = Pd or Pt, dba = dibenzylideneacetone), R = Cy or Ph. Thezerovalent platinum complex [Pt(PPh(3)){(Cy(2)PCH(2))(2)NMe}] can be obtained by hydrazine hydrate reduction of a mixture of [PtCl2{(Cy(2)PCH(2))(2)NMe}] and triphenylphosphine or one of cis-[PtCl2(PPh(3))(2)] and (Cy(2)PCH(2))(2)NMe. The crystal structure of [Pd(dba){(Cy(2)PCH(2))(2)NMe}] has been determined and some reactions of the complexes are reported. [References: 11]
