practical, rapid, and efficient microwave (MW) promoted synthesis of various azides, thiocyanates, and sulfones is described in an aqueous medium. This general and expeditious MW-enhanced nucleophilic substitution approach uses easily accessible starting materials such as halides or tosylates in reaction with alkali azides, thiocyanates, or sulfinates in the absence of any phase-transfer catalyst, and
在水性介质中描述了实用,快速且有效的微波(MW)促进的各种叠氮化物,硫氰酸盐和砜的合成。这种通用且快速的增强MW的亲核取代方法在不存在任何相转移催化剂的情况下,使用易于获得的起始原料(例如卤化物或甲苯磺酸盐)与碱金属叠氮化物,硫氰酸盐或亚磺酸盐进行反应,并且可以耐受多种反应性官能团。
