摘　　要：本文合成了含磷硫杂配位原子配体的Pt金属有机配合物,并对PtCl_2[Ph_2P(CH_2)_2SCH_3]配合物进行了晶体和分子结构测定。研究了这些Pt金属配合物对苯的C—H键的活化作用,考察了对苯的光羰化反应性能。Some new complexes containing phosphorus and sulfur hybrid ligands have been prepared and characterized by IR and elemental analyses. They are PtCl_2[R^1_2P(CH_2)_2SR] (R=CH_3, Et, Ph; R^1=Ph, Et). Among these complexes, the molecular structure of PtCl_2[Ph_2P(CH_2)_2SCH_3] has been determined crystallographically by X ray diffraction. The photochemical carbonylation of benzene catalyzed by above complexes has been studied under 101325 Pa of carbon monoxide at room temperature. The benzaldehyde of reaction product was identified by the gas chromatograph-mass spectrometry. In addition, we also have suggested the mechanism of photochemical carbonylation of benzene.
