摘要

报道了一种铁催化的一锅串联原位氧化- wittig反应合成烯烃。采用稳定的Fe（II）催化剂和氧化还原-非氧化还原- 2 -（（4 -氯苯基）二氮基）- 1,10 -菲罗啉配体支架，通过醇类与磷酰化物的反应，以较高的收率合成了广谱取代E -烯烃。对照反应和光谱研究表明，在醇与磷酰化物的脱氢偶联过程中，配体作为电子和氢的储存库参与了协同作用。

Metal–Ligand Cooperation for Iron(II)‐Catalyzed Direct Wittig‐Type Olefination from Alcohols in Air

An iron‐catalyzed one‐pot tandem in situ oxidation–Wittig reaction is reported for the synthesis of alkenes. Using a bench‐stable Fe(II) catalyst with a redox‐noninnocent 2‐((4‐chlorophenyl)diazenyl)‐1,10‐phenanthroline ligand scaffold, a broad spectrum of substituted E olefins were synthesized in good yields by the reaction of alcohols with phosphorus ylides. Control reactions and spectroscopic studies indicate synergistic participation of the ligand, which acts as a reservoir of electrons and hydrogen, during the dehydrogenative coupling of alcohols with the phosphorus ylides.
