One-pot three components synthesis of O-acetylcyanohydrins has been developed in the presence of B(C6F5)3 as the catalyst. Variety of aldehydes or ketones reacts with TMSCN and acetic anhydride (Ac2O) under the influence of 1 mol % of B(C6F5)3 to give good to excellent yield of the products without solvent at rt.
在存在B(C 6 F 5)3作为催化剂的情况下,已经开发了O-乙酰基氰醇的一锅三组分合成法。在1摩尔%的B(C 6 F 5)3的影响下,各种醛或酮与TMSCN和乙酸酐(Ac 2 O)反应,从而在室温下在不使用溶剂的情况下获得了良好的优异收率。
