Some new complexes containing P and S hybrid ligands were prepared and characterized by IR and elemental analyses. They are PtCl2[R12P(CH2)2SR] (R = Me, Et, Ph; R1 = Ph, Et). Among these complexes, the mol. structure of PtCl2[Ph2P(CH2)2SMe] was determine crystallog. by x-ray diffraction. The photochem. carbonylation of benzene catalyzed by above complexes was studied under 101,325 Pa of CO at room temperature The benzaldehyde reaction product was identified by gas chromatograph-mass spectrometry. The authors also suggest a mechanism of photochem. carbonylation of benzene.
