Abstract
The platinum(IV) complex [PtIMe(3)(Me(3)Si)(bpy)](bpy = 2,2'-bipyridin e) undergoes thermal decomposition (177-195 degrees C) to give Me(4)Si and [PtIMe(bpy)]. Differential scanning calorimetry (DSC) shows the h eat of reaction for this process to be -8 +/- 5 kJ mol(-1). Using publ ished bond energy data for Pt-Me and Si-Me, we obtain. a D(Pt-SiMe(3)) of 233 +/- 14 kJ mol(-1). This is the first experimental estimation o f D(Pt-SiMe(3)). The Pt-Si bond is approximately 100 KJ mol(-1) strong er than the Pt-CH3 bond energy.
