method for the first direct insertion of difluorcarbene, generated from TMSCF3, into diselenides and disulfides is disclosed, producing novel difluoromethyl diselenoacetals and difluoromethyl dithioacetals. The reaction conditions tolerate a range of synthetically useful and biologically relevant functional groups. The process is scalable, with two representative compounds prepared at a gram-scale in
公开了一种将由TMSCF 3产生的二氟卡宾首次直接插入二硒化物和二硫化物中的方法,该方法产生了新型的二氟甲基二硒缩醛和二氟甲基二硫缩醛。反应条件容许一系列合成上有用的和生物学上相关的官能团。该方法是可扩展的,以克为单位以高收率制备了两种代表性化合物,并且使用了便宜且可用的试剂。
