Concerted E2 mechanism for the base hydrolysis of cis-[CoCl2(cyclen)]+
Abstract
Evidence is presented in support of a concerted E2 mechanism for the base hydrolysis of cis-[CoCl2(cyclen)]+(cyclen = 1,4,7,10-tetra-azacyclododecane) in which cleavage of the N–H and Co–Cl bonds occurs synchronously to give a five-co-ordinate intermediate without the intervention of a six-co-ordinate conjugate base.
