An increasing number of reactions of sulfenic acid anions are being demonstrated in the literature. As such, mild, general and reliable means for the generation of sulfenates are due. In the current paper, an addition/elimination of 2-sulfinyl acrylates using various nucleophiles is demonstrated and evaluated as a protocol for alkane- and arenesulfenate generation. Cyclohexanethiolate, methoxide and
文献中已证明亚磺酸阴离子的反应越来越多。因此,应采用温和,通用和可靠的方法生成亚磺酸盐。在当前的论文中,使用各种亲核试剂证明了丙烯酸2-亚磺酰基酯的添加/消除作用,并作为生成链烷烃和芳烃磺酸盐的方法进行了评估。环己烷硫醇盐,甲醇盐和正丁基锂在反应中各有优点,硫醇盐是一种温和,选择性和有效的试剂,可从丙烯酸2-亚磺酰基酯中释放出亚硫酸盐。认识到每个亲核试剂的添加/消除的立体特异性,并且提供了对硫醇盐和甲醇盐的特异性的解释。
