Fung, Hong Sang Li, Bao Zhu Chan, Kin Shing Sterically Enhanced, Selective C(CO)−C(α) Bond Cleavage of a Ketones by Rhodium Porphyrin Methyl Selective carbon(CO)−carbon(α) bond activation of ketones was achieved by rhodium(III) 5,10,15,20-tetrakis-4-toylporphyrinato methyl (Rh(ttp)Me (<b>1</b>)) to yield the corresponding rhodium porphyrin acyls at temperatures as low as 50 °C. More hindered isopropyl ketones were much more reactive than ethyl or methyl ketones. Rh(ttp)OH (<b>3a</b>) was proposed to be the intermediate to cleave the C(CO)−C(α) bond.
