An efficient metal-free synthesis of 1,1-dithio-1-alkenes from 1,1-dibromo-1-alkenes and thiols using a diazabicycloundecene/dimethyl sulfoxide system was developed. The method was found suitable for various 1,1-dibromo-1-alkenes. The synthesis was completed within 5-15 minutes at room temperature with moderate to excellent yields.
开发了一种高效的无金属合成方法,通过二溴代1-烯烃和硫醇在二氮杂双环十一烯/二甲基亚砜体系中合成1,1-二硫代-1-烯烃。该方法适用于多种1,1-二溴代1-烯烃。该合成在室温下可以在5-15分钟内完成,产率中等至优秀。
