arylation of aromatic carbonyl compounds is reported. The use of 4 % FeCl3 or Fe(acac)3 as the catalyst, in combination with a slight excess of chlorotrimethylsilane and triethylsilane, chlorination of benzylic ketones and aldehydes with subsequent Friedel–Crafts alkylation of arenes is achieved. Although the method is limited by the general constraints associated with Friedel–Crafts alkylation reactions
报道了一种简单有效的铁催化芳族羰基化合物芳基化方法。使用 4% FeCl3 或 Fe(acac)3 作为催化剂,结合略微过量的三甲基氯硅烷和三乙基硅烷,实现苄基酮和醛的氯化,随后芳烃的 Friedel-Crafts 烷基化。尽管该方法受到与 Friedel-Crafts 烷基化反应相关的一般约束的限制,但可以设想在药物中间体等方面的稳健应用。
