ABSTRACT An efficient ultrasound-promoted thiocyanation of phenols, indoles, and anilines in the presence of N-chlorosuccinimide and NH4SCN using 1,1,1,3,3,3-hexafluoro-2-propanol as the solvent has been developed. The major features of the present protocol include the mild reaction conditions, short reaction times, good to excellent yields, and broad substrate scope. Moreover, scale-up synthesis can
摘要 使用 1,1,1,3,3,3-六氟-2-丙醇作为溶剂,在 N-氯琥珀酰亚胺和 NH4SCN 存在下,一种高效的超声促进苯酚、吲哚和苯胺硫氰化反应已被开发出来。本协议的主要特点包括温和的反应条件、较短的反应时间、良好的产量和广泛的底物范围。此外,可以实现放大合成,并且溶剂可以很容易地回收和再利用。图形概要
