Amine‐Activated Iron Catalysis: Air‐ and Moisture‐Stable Alkene and Alkyne Hydrofunctionalization

A simple alkylamine [(iPr)2NEt] has been used to activate an air- and moisture-stable iron(II) pre-catalyst for alkene and alkyne hydrofunctionalization reactions. This amine activation has enabled the highly operationally simple hydrosilylation and hydroboration of alkenes and alkynes using just 0.25–2 mol% iron catalyst and 1–25 mol% amine. Significantly, these reactions proceed in equal yield under both air and inert reaction conditions.
