Gallium chloride catalyzed acylation of alkynes was studied to afford one of the most atom-economic and efficient methodologies for the preparation of β-chlorovinyl ketones. In contrast to the Friedel-Crafts acylation, only a catalytic amount of GaCl3 was needed to produce the target products in high stereoselectivity.
研究人员对氯化镓催化的炔烃酰化反应进行了研究,以获得制备δ-氯乙烯酮的最经济、最有效的方法之一。与弗里德尔-卡夫斯酰化法相比,只需要少量的氯化镓催化剂就能以高立体选择性制备目标产物。
