Porphyrinatoiron-catalysed reduction of styrene with sodium borohydride: proposed σ-alkyliron(III) complex as an intermediate
Abstract
5,10,15,20-Tetrakis(para-substituted phenyl)porphyrinatoiron(III) chloride complexes catalyse the reduction of styrene with NaBH4 to ethylbenzene and 2,3-diphenylbutane and the precursor is assumed to be the σ-alkyl complex (Xtpp)FeIII–PhCHMe.
