Abstract
Reduced cobalt catalysts effect selective 1,2-, 1,4-, or 4,3-additions of pinacolborane to various 1,3-dienes depending on the ligands chosen. Regio- and enantioselective 1,2-hydroborations of 2-substituted 1,3-dienes are best accomplished using a catalyst prepared via activation of a chiral phosphinooxazoline-cobalt(II) complex with zinc and NaBARF.
