摘要

The mechanism of the electroreductive coupling of a-chloro esters or a-chloro nitriles with carbonyl compounds by the means of a sacrificial zinc anode and a nickel catalyst was elucidated by electroanalytical techniques. The mechanism involved reduction of a Ni (I1) complex to a Ni (0) complex, oxidative addition of the a-chloro ester to the Ni (0) complex, and a Zn (II)/Ni (II) exchange, leading to an organozinc Reformatsky reagent. The ...
