A transition-metal-free arylation of lithium, magnesium, and zinc sulfinates with diaryliodonium salts is described. The sulfinic acid salts were prepared from the reaction of the corresponding organometallic reagents and sulfur dioxide. Combination of the three single steps (preparation of the organometallic compound, sulfinate formation, and arylation) leads to a one-pot sequence for the synthesis
描述了锂,镁和锌亚磺酸盐与二芳基碘鎓盐的无过渡金属芳基化。亚磺酸盐是由相应的有机金属试剂与二氧化硫反应制得的。三个单一步骤(有机金属化合物的制备,亚磺酸盐的形成和芳基化)的组合产生了从简单起始原料合成芳基砜的一锅法序列。已经研究了不对称二芳基碘鎓盐的化学选择性。将讨论这种方法的潜力和局限性。
