A novel, practical and highly efficient method for the construction of a variety of sulfonamides mediated by I2 was demonstrated. The reaction proceeds readily at room temperature using a variety of sodium sulfinates and amines or ammonia in water in a metal-, base-, ligand-, or additive-free protocol. Primary, secondary and tertiary sulfonamides were obtained in good to excellent yields with a broad
证明了一种新颖,实用,高效的方法来构建由I 2介导的多种磺酰胺。在室温下,使用各种亚磺酸钠和胺或水中的氨,按照无金属,无碱,无配体或无添加剂的方案,可以轻松地进行反应。伯,仲和叔磺酰胺的收率高至优异,并且具有宽泛的官能团耐受性。
