Sulfilimines are key intermediates to common motifs in medicines and agrochemicals. Typically, this class of compounds are prepared by imidation of thioethers, transition-metal-catalyzed or base-promoted sulfur alkylation and transition-metal-catalyzed sulfur arylation. Here, we report a practical and efficient base-mediated sulfur arylation reaction for the preparation of sulfilimines. A wide range
硫亚胺是药物和农用化学品中常见基序的关键中间体。通常,这类化合物是通过硫醚的酰亚胺化、过渡金属催化或碱促进的硫烷基化和过渡金属催化的硫芳基化制备的。在这里,我们报告了一种用于制备硫亚胺的实用且有效的碱介导硫芳基化反应。范围广泛的N-酰基和N-芳基亚磺酰胺与各种二芳基碘盐顺利反应,以高产率提供具有优异化学选择性的硫亚胺。
