A Ni-catalyzed reductive cross-coupling of alpha-hydroxycarbonyl compounds modified with oxalyl groups and aryl halides has been developed that furnishes alpha-aryl esters under mild conditions and tolerates a variety of functionalized aryl halides bearing electron withdrawing and-donating groups. This work highlights C-O bond fragmentation on secondary alkyl carbon centers that generates alpha-carbonyl radicals.

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
