Cobalt- and Iron-Catalyzed Regiodivergent Alkene Hydrosilylations


A complementary set of base metal catalysts has been developed for regiodivergent alkene hydrosilylations: iron complexes of amine-iminopyridine ligands are selective for Markovnikov hydrosilylations (branched/linear up to >99:1), while the cobalt complexes bearing the same type of ligands provide excellent levels of anti-Markovnikov selectivity (linear/branched up to >99:1). Both systems exhibit high efficiency and wide functional group tolerance.
