Herein, we report a new method for the one-pot synthesis of 1,1-dihydrofluoroalkyl sulfides by bubbling sulfuryl fluoride (SO2F2) through a solution of the corresponding alcohol and thiol. The reaction proceeds through a new class of bis(1,1-dihydrofluoroalkyl) sulfate reagents, to afford the desired 1,1-dihydrofluoroalkyl sulfides in 55-90% isolated yields. The bis(1,1-dihydrofluoroalkyl) sulfates
在此,我们报道了一种通过将硫酰氟(SO2F2)鼓泡通过相应的醇和硫醇的溶液来一锅合成1,1-二氢氟烷基硫醚的新方法。该反应通过一类新型双(1,1-二氢氟烷基)硫酸盐试剂进行,以 55-90% 的分离产率提供所需的 1,1-二氢氟烷基硫醚。双(1,1-二氢氟烷基)硫酸盐对硫醇烷基化具有高度化学选择性,并且不与竞争性的、未保护的亲核试剂(包括胺、醇和羧酸)发生反应。
