Iron-catalysed alkene hydrogenation and reductive cross-coupling using a bench-stable iron(ii) pre-catalyst

Abstract

Operationally simple, iron-catalysed hydrogenation and reductive cross-coupling protocols have been developed using a bench-stable iron(II) pre-catalyst. The hydrogenation of 18 alkenes (50–99%) and reductive cross-coupling of vinyl halides with aryl- and alkyl Grignard reagents (8 examples, 18–99%) is reported using 3 mol% pre-catalyst and hydrogen as stoichiometric reductant (1–50 bar).
