A very active cobalt catalyst enables a facile anti-Markovnikov hydroboration of sterically hindered terminal alkenes. Notably, these hydroboration reactions proceed in neat substrates at 23°C. With internal olefins, the cobalt catalyst provides a convenient method for hydrofunctionalization of remote C-H bonds by placing the boron substituent exclusively at the terminal positions of an alkyl chain.
