Abstract

Abstract: The iron complex ( iPr PN Me P)Fe(H)2 (CO) ( iPr PN Me P=CH3 N(CH2 CH2 P i Pr2 )2 ), which features a pincer ligand with a tertiary amine, can give up to 100, 000 turnovers for additive‐free formic acid dehydrogenation (FADH). This is two orders of magnitude higher than any previously reported base metal system. Mechanistic studies reveal the catalytic reaction pathway and provide guidance for the development of improved catalytic systems for additive‐free FADH. Abstract : Highly productive Fe complexes : The activity of an iron complex containing a pincer ligand with a tertiary amine for additive‐free formic acid dehydrogenation is reported. This complex gives up to 100, 000 turnovers, which is higher than any other additive‐free base metal system. Experimental and computational studies reveal the mechanistic basis for the high productivity.
