AB The protonolysis of C–Au bonds in [AuRL] organometallic complexeshas been studied by calorimetry for twelve R groups. The experimental datahave been combined with DFT calculations to obtain Bond Dissociation Energyvalues (BDE). The C–Au BDE values show a good correlation with the correspondingisolobal C–H BDE values. The heat released in the protonolysis of[AuRL] has also been measured for R = Ph and L = P(OPh)3, PPh3, PMe3, PCy3,and IPr, and these values strongly depend on the trans influence of L because of themutual destabilization of the L–Au and Au–C bonds. The enthalpy of thetransmetalation reactions [AuR(PPh3)] + SnIBu3 → [AuI(PPh3)] + SnRBu3 forseven R groups have been measured and compared with the corresponding[AuR(PPh3)] protonolysis.
