Oxidative Addition of a Strained C–C Bond onto Electron-Rich Rhodium(I) at Room Temperature

The C–C bond of cyclobutanones undergoes oxidative addition to a T-shape rhodium­(I) complex possessing a PBP pincer ligand at room temperature. The remarkable propensity of the rhodium complex for oxidative addition is attributed to the highly electron-donating nature of the boron ligand as well as the unsaturation on the rhodium center.

室温下，环丁酮的碳-碳键可与带有PBP钳形配体（PBP pincer ligand）的T形铑(I)配合物发生氧化加成（oxidative addition）反应。该铑配合物在氧化加成反应中展现出的优异活性，可归因于其硼配体的强给电子特性以及铑中心的配位不饱和性。
