Abstract

Reaction of iron(0) carbene complexes with hexafluorobut-2-yne produces 3,4-bis(trifluoromethylated)furans in a process that is favored for electron rich carbenes. No traces of furannulation or benzannulation are observed with Group 6 Fischer carbenes. Reaction of hexafluorobut-2-yne with a vinylketene iron(0) complex gives a 2,3-bis-trifluoromethylated phenol.

摘要

零价铁卡宾配合物与六氟-2-丁炔反应生成3,4-双(三氟甲基化)呋喃,该过程有利于富电子卡宾。对于第6族菲舍尔卡宾,未观察到呋喃化或苯并环化的痕迹。六氟-2-丁炔与乙烯基乙烯酮零价铁配合物反应生成2,3-双三氟甲基化苯酚。
