摘要：

The complex [PtMe2(μ-SEt2)]2 undergoes oxidative addition reactions with chloro-2,2-bis(pyrazol-1-yl)propanes and 2,6-(pzCH2)2C6H3Br to form platinum(IV) complexes PtClMe2{(pz)2CR(CHX)-N,N′,C″} and PtBrMe2{2,6-(pzCH2)2C6H3-N,N′,C″1}, respectively, with the ligands present as tripodal [N-C-N]- systems. Structural studies of two of the complexes show distorted octahedral geometry, 'fac-PtClC3N2', with (pz)2CMeCH2- and (pz)2C(CH2Cl)CH2- forming NPtN and NPtC angles at platinum ca. 7-12° less than 90°. The reagent 1,3-(pzCH2)2C6H4 undergoes cyclomellation with palladium(II) acetate to form Pd(O2CMe){2,6-(pzCH2)2C6H3-N,N′,C″1}, which has the ligand present as a planar [N-C-N]- donor. © 1990.
