We herein report an unprecedented xanthate-based protocol for the preparation of aryl-alkyl thioethers. Heating xanthates with aryl halides and namely cesium carbonate in methanol provides the target thioethers in generally good yields within short reaction times. This method allows one to avoid contact with odorous thiols and also to introduce substituents of which the corresponding thiols are virtually
我们在此报告了一种前所未有的基于黄原酸盐的制备芳基-烷基
硫醚的方案。用芳基卤化物加热黄原酸酯,即
甲醇中的
碳酸铯,可在较短的反应时间内以通常良好的产率提供目标
硫醚。这种方法可以避免与有气味的
