Determination of Rh–C Bond Dissociation Energy in Methyl(porphyrinato)rhodium(III) Complexes: a New Application of Photoacoustic Calorimetry

The photolysis of RhCH3(ttp) and RhCH3(tmp) (ttp = 5,10,15,20-tetratolylporphyrin, tmp = 5,10,15,20-tetramesitylporphyrin) was studied in methanol at ambient temperature: the quantum yields for photolysis were determined to be 0.51 and 0.54, respectively, and the Rh–C bond dissociation energies (227...

Description
Summary:The photolysis of RhCH3(ttp) and RhCH3(tmp) (ttp = 5,10,15,20-tetratolylporphyrin, tmp = 5,10,15,20-tetramesitylporphyrin) was studied in methanol at ambient temperature: the quantum yields for photolysis were determined to be 0.51 and 0.54, respectively, and the Rh–C bond dissociation energies (227 and 219 kJ mol−1, respectively) were measured by photoacoustic calorimetry, which were larger than those of Co–C bond.
