Facile iron-catalyzed cleavage of various allyl, cinnamyl and benzyl CâO linkages has been effected in the presence of ethylmagnesium chloride. The protocol is operationally simple (xyleneâTHF, r.t., 1 h), requires low catalyst loading (1 mol% FeCl2) and tolerates halides, esters, amines, ethers and olefins. The allyl moiety is converted to volatile hydrocarbons which renders laborious product separation unnecessary.
在乙基镁氯的存在下,容易用铁催化剂切断各种烯丙基、肉桂基和苄基的C–O键。该方法操作简单(用二甲苯–四氢呋喃,在室温下反应1小时),所需催化剂用量低(1 mol% FeCl2),并且对卤素、酯、胺、醚和烯烃具有耐受性。烯丙基部分转化为挥发性烃,省去了繁琐的产品分离步骤。
