Question:

The Reformatsky reaction is an addition reaction in which an organozinc reagent is used instead of a Grignard reagent to attack the carbonyl group of an aldehyde or a ketone. Because the organozinc reagent is less reactive than a Grignard reagent, a nucleophilic addition to the ester group does not occur. The organozinc reagent is prepared by treating an a-bromo ester with zinc.
The Reformatsky reaction is an addition reaction in which an
