Olefin hydroboration catalyzed by an iron-borane complex

Abstract

The well-defined iron(0) complex [(^iPrDPB^Ph)Fe₂-(μ-1,2-N₂)] (A) reacts with HBpin to afford the complex [(η³-H₂^iPrDPB)Fe(η³-H₂Bpin)] (B) via oxidative addition of the H–B bond. Complex A is an effective pre-catalyst for the hydroboration of a range of olefins in synthetically useful yields (typically >80%) under neat conditions.
