WCl6 was used as a novel, efficient and reusable catalyst for the preparation of N-sulfonyl imines via the condensation of sulfonamides with aldehydes as well as isatin under solvent-free conditions. The turn-over frequency (TOF) value of the catalyst is several times higher than the previously reported catalysts. Clean reaction, simple purification, short reaction time and high yield are some other
WCl 6用作新型,高效和可重复使用的催化剂,用于通过磺酰胺与醛的缩合以及N-磺酰亚胺的缩合反应制备N-磺酰基亚胺。伊斯丁在无溶剂条件下。催化剂的周转频率(TOF)值是以前报道的催化剂的几倍。干净的反应,简单的纯化,短的反应时间和高收率是这项工作的其他优点。
