Reformatsky Reaction – Full Reaction Mechanism Explained

Reformatsky Reaction

Reformatsky reaction is a formation of ß-hydroxy ester when treating ɑ-halo ester with zinc metal in presence of an inert solvent,

Reaction Mechanism of Reformatsky Reaction

In the first step, Zinc metal (0) is reacted with ɑ-halo ester and forms an organo-zinc complex which is simply known as Reformatsky enolate. It is very much similar to a Grignard reagent, It is added to Carbonyl compound and it forms a ß-hydroxy ester
This naming reaction is also undergoing dehydration same as Perkin, aldol reactions to give ɑ, ß – unsaturated esters.Reformatsky reaction mechanism,
