摘要

Abstract We have succeeded in developing zinc borates of the general structure 3 for coupling reaction with allylic acetates. The advantages of using compounds 3 are their compatibility with carbonyl groups such as aldehyde, ketone, and ester groups, and their high reactivity toward secondary allylic acetates. Zinc borates 3 were prepared from boronate esters 1 [RT= p-(CHO) C 6 H 4, p-(Ac) C 6 H 4, p-{Ac (CH 2) 2} C 6 H 4, p-( ...
