A novel, rapid, and environmentally-friendly protocol for the synthesis of sulfonamides using iodine as catalyst under solvent-free conditions is described. This method involves the oxidative coupling of sulfonyl hydrazides and amines in the presence of catalytic amount of iodine using TBHP as oxidant. This protocol does not require purification techniques such as column chromatography and recrystalization
描述了一种在无溶剂条件下使用碘作为催化剂合成磺酰胺的新颖,快速且环境友好的方案。该方法涉及在使用TBHP作为氧化剂的催化量碘存在下,磺酰肼和胺的氧化偶联。该方案不需要纯化技术,例如柱色谱法和重结晶法。
