Manoj D Patil,Kiron Kumar Ghosh,T. V. RajanBabu +2 more
TL;DR: Researchers develop cobalt-catalyzed enantioselective hydroboration of α-substituted acrylates, yielding β-borylated propionates with high regio- and enantioselectivity, and propose a mechanism involving oxidative migration of a boryl group to the β-carbon of an η4-coordinated acrylate-cobalt complex.
