unsymmetrical sulfides from esters and thiols in the presence of InI3 and either 1,1,3,3-tetramethyldisiloxane (TMDS) or PhSiH3 as the reductant was developed. This protocol was applied to not only benzoic acid esters that have a methoxy, methyl, chloro, bromo, iodo, or trifluoromethyl group on the aromatic ring but also aliphatic acid esters with either aromatic or aliphatic thiols. A reaction mechanism
在 InI3 和 1,1,3,3-四甲基二硅氧烷 (TMDS) 或 PhSiH3 作为还原剂的存在下,开发了一种新的由酯和硫醇还原制备不对称硫化物的方法。该方案不仅适用于在芳环上具有甲氧基、甲基、氯、溴、碘或三氟甲基的苯甲酸酯,还适用于具有芳香或脂肪硫醇的脂肪酸酯。通过使用哈米特图结果和几个控制实验提出了反应机制。
