Iron-Catalyzed, Markovnikov-Selective Hydroboration of Styrenes

A highly Markovnikov-selective, iron-catalyzed hydroboration of styrenes is reported using available oxazolinylphenyl picolinamide as the ligand to afford the branched hydroboration products with up to >50/1 b/1. This reaction is operationally simple and could be carried out in gram scale.
