Abstract
The thiaplatinacycles, [PtL2(C,S–C12 H8S)] and [PtL2(C,S–C13H10S)] (L = PEt3, PMe3; L2=Ph2PCH2 CH2PPh2), obtained from oxidative insertion of [Pt0Ln] into dibenzothiophene and 4-methyldibenzothiophene are hydrodesulfurized by reaction with hydrogen (toluene, 20 atm, 100°C) to biphenyl and 3-methylbiphenyl, respectively; addition of acidic alumina improves the reaction. These observations link the model systems and the latest generation of commercial second-stage HDS catalysts.
