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

Tris(dibenzylideneacetone)dipalladium and bis(dibenzylideneacetone)pla tinum re act with N, N-bis(dicyclohexylphosphinomethyl)methylamine, (C y(2)PCH(2))(2)NMe (Cy = cyclohexyl), and with N, N-bis(diphenylphosphi nomethyl)methylamine, (Ph(2)PCH(2))(2)NMe (Ph = phenyl), to give the c omplexes [M(dba){(R(2)PCH(2))(2)NMe}] (M = Pd or Pt, dba = dibenzylide neacetone), 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 o ne of cis-[PtCl2(PPh(3))(2)] and (Cy(2)PCH(2))(2)NMe. The crystal stru cture of [Pd(dba){(Cy(2)PCH(2))(2)NMe}] has been determined and some r eactions of the complexes are reported.
