We report the synthesis of sulfinamides using organometallic reagents, a sulfur dioxide reagent, and nitrogen based-nucleophiles. The addition of an organometallic reagent to the commercially available sulfur dioxide surrogate, DABSO, generates a metal sulfinate which is reacted with thionyl chloride to form a sulfinyl chloride intermediate. Trapping the sulfinyl chlorides in situ with a variety of
我们报告了使用有机金属试剂,二氧化硫试剂和氮基亲核试剂合成亚磺酰胺的方法。将有机金属试剂添加到可商购的二氧化硫替代物DABSO中,生成金属亚磺酸盐,该金属亚磺酸盐与亚硫酰氯反应形成亚磺酰氯中间体。用各种氮亲核试剂原位捕获亚磺酰氯,可得到32-83%的亚磺酰胺。该过程的每个阶段均在室温下进行,总反应时间仅为1.5 h。
