摘要
The relative rates of oxidative addition of secondary carbohydrate iodides 2, 5, and 7 with [py(dmgH)2Co(I)]-, to form mixtures of diastereomeric alkyl cobaloximes 3 and 8, are consistent with steric inhibition of the electron-transfer step. On the basis of these and previously reported observations, a unified mechanism for oxidative addition is proposed.
