Iron-catalysed, general and operationally simple formal hydrogenation using Fe(OTf)3 and NaBH4

Org Biomol Chem. 2014 Jul 28;12(28):5082-8. doi: 10.1039/c4ob00945b.

Abstract

An operationally simple and environmentally benign formal hydrogenation protocol has been developed using highly abundant iron(iii) salts and an inexpensive, bench stable, stoichiometric reductant, NaBH4, in ethanol, under ambient conditions. This reaction has been applied to the reduction of terminal alkenes (22 examples, up to 95% yield) and nitro-groups (26 examples, up to 95% yield). Deuterium labelling studies indicate that this reaction proceeds via an ionic rather than radical mechanism.
