铁配合物（（PNP）-P-iPr-P-Me）Fe（H）（2）（CO）（（PNP）-P-iPr-P-Me= CH 3 N（（CH 2CH 2 PPr 2）-Pr-1）（2））的特征在于具有叔胺的钳形配体，对于无添加剂的甲酸脱氢（FADH）可以给出高达100，000次的转化。这比以前报道的任何贱金属系统高两个数量级。机理研究揭示了催化反应途径，并为开发无添加剂的FADH改进催化体系提供指导。
The iron complex ((PNP)-P-iPr-P-Me)Fe(H)(2)(CO) ((PNP)-P-iPr-P-Me=CH3N((CH2CH2PPr2)-Pr-i)(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.
