| Abstract: | The parallel lability trend for the anation reactions of RRh(DH)2H2O (RCH3, CH3CH2, CF3CH2, ClCH2) and RCo(DH)2H2O complexes suggests a dissociative activation process for the reactions of the organorhodoximes. The high lability of these complexes, arising from the stabilization of the transition state, is not entirely due to the trans-effect of the R group, but, at least partially, to the labilizing effect of the equatorial macrocycle. |
