Abstract
The photochemistry of the complexes trans-trans monohydrido-bridged [(PEt3)2HPt(μ-H)PtH(PEt3)2][BPh4] (1) and trans-cis dihydrido-bridged [(PEt3)2HPt(μ-H)2Pt(PEt3)2] [BPh4] (2) is reported. Photolysis of 1 and 2 using 334-nm light occurs with good quantum yields to give irani-[PtH2(PEt3)2] (3a) and (ra/i5-[PtH(S)(PEt3)2]+(4) (S = solvent, e.g. acetonitrile). Photoproducts 3a and 4 are highly reactive and undergo a multiplicity of reactions depending upon experimental conditions. Evidence of H2elimination, photoinduced insertion of C02into the Pt-H bond of 3a, and abstraction of CI from chlorocarbon solvents by 3a and 4 is reported. © 1990, American Chemical Society.
