摘要：
Displacement of cod from [Pt(cod)Cl-2] by 2 equiv. of heteroarylphosphorus ligand, PR2R' in dichloromethane at ambient temperature afforded - but for one exception trans-[Pt(P {2-(N-methylpyrrolyl)}Pr-i(2))(2)Cl-2] (1) - the expected cis complexes, cis -[Pt(P {2-(N-methylpyrrolyl)}Ph-2)(2)Cl-2] (2), cis-[Pt(P {2-(5-methylthienyl)}R-2)(2)Cl-2] (R = Ph 3,Pr-i 4) and cis-[Pt(P{ 2-(5-bromopyridinyl)}Pr-i(2))(2)Cl-2] (5). The complexes were fully characterised and structural assignments were based on (1)J(Pt-195-P-31) coupling constants from the NMR data. The structure of 1 was determined by X-ray crystallography, which revealed that the two pyrrolyl substituents on the phosphine ligands were oriented on opposite sides of the P-Pt-P axis.
