intermolecular difunctionalization strategy of styrenes with methyl thiosulfonates and arylboronic acids has been developed. This method provides an efficient and straightforward avenue to a broad range of 2,2-diarylethyl sulfone derivatives from readily available methyl thiosulfonates and commercially available styrene and arylboronic acid derivatives. The diverse substrate scope attests to the high
已经开发了一种通用且实用的苯乙烯与硫代磺酸甲酯和芳基硼酸的铜催化的分子间双官能化策略。该方法为从容易获得的甲基硫代磺酸甲酯和市售的苯乙烯及芳基硼酸衍生物中广泛的2,2-二芳基乙基砜衍生物提供了一种有效而直接的途径。不同的底物范围证明了该反应的高官能团耐受性。该协议的温和性质使其适用于生物活性天然产物的后期功能化。机理研究支持了磺酰基自由基的作用并证实了铜催化的自由基中继途径。
