Ni-catalyzed activation of α-chloroesters: a simple method for the synthesis of α-arylesters and β-hydroxyesters
Coupling reactions of α-chloroesters with aryl halides (α-arylation) or carbonyl compounds (Reformatsky) using nickel catalyst allow, under mild conditions, the preparation of various functionalized aryl propionic acid derivatives or β-hydroxyesters. In the synthesis of aryl propionic acid derivatives, the process is efficient with aryl halides bearing either electron-withdrawing or electron-donating groups.

Iron-catalysed Reformatsky-type reactions
A Reformatsky-type reaction has been developed using iron catalysis in acetonitrile or DMF. Reduction of iron(II) bromide by manganese metal in acetonitrile provides a low-valent iron catalyst, which is the active species; under these conditions, α-chloro

Iron-mediated electrochemical reaction of α-chloroesters with carbonyl compounds
(Matrix presented) Reformatsky-type reactions have been performed efficiently using an electroassisted iron-complex catalysis. Valuable product such as β-hydroxyesters, ketones or nitriles are thus prepared with high yields.

ELECTROREDUCTIVE COUPLING OF METALLYLCHLORIDE OR METHYL CHLOROACETATE WITH CARBONYL COMPOUNDS CAATLYZED BY NICKEL BIPYRIDINE COMPLEXES
An efficient electrosynthesis of homoallyl alcohols or β-hydroxy esters in the presence of catalytic amounts of the NiBr2(2,2'-bipyridine) complex has been developed from mixed electrolysis of metellylchloride, or methyl chloroacetate with several carbonyl compounds, using a one-compartment cell equiped with a sacrificial zinc anode.
