FeCl3(Py)4, FeCl3[(NH2)2CO]6 and FeCl3[(NH2)2CS]6 as Efficient Catalysts for the Efficient Reduction of Carbonyl Compounds with NaBH4 under Apr

Abstract

FeCl₃(Py)₄, FeCl₃[(NH₂)₂CO]₆ and FeCl₃[(NH₂)₂CS]₆ are   used as efficient catalysts for reduction of a variety of carbonyl   compounds such as aldehydes, ketones, acyloins, α-diketones   and conjugated carbonyl compounds with NaBH₄ under   aprotic condition. The corresponding alcohols are obtained   in high to excellent yields. Reduction reactions are performed   in CH₃CN at room temperature or reflux.
