Abstract: The thermolyses of (tBuP(O)N)PtMe2 (1, tBuP(O)N = (di-tert-butylphosphinito)pyridine) and (tBuP(N–H)N)PtMe2 (3, tBuP(N–H)N = (di-tert-butylphosphino)-2-aminopyridine) in benzene-d6 were investigated. With (tBuP(O) N)PtMe2, the product of a rollover cyclometalation of the pyridyl ring was observed in 80% yield along with formation of CH4. In contrast, thermolysis of (tBuP(N–H)N)PtMe2 resulted in competing rollover cyclometalation and intermolecular benzene C–H activation with production of a mixture of CH4 and CH3D
