The first example of a smooth, practical and useful strategy for the preparation of ortho-aryl/alkyl sulfenyl phenols by using the reaction of aryl/alkyl thiols with phenols in the presence cobalt as catalyst, and with the assistance of acetic anhydride as directing group via CH bond activation, was developed. Described method enables to form selectively CS bond without any ligand, oxidant, and aryl/alkyl
通过在芳族钴存在下使用芳基/烷基硫醇与苯酚的反应作为催化剂,并以乙酸酐为指导基团,制备邻-芳基/烷基亚硫基苯酚的平稳,实用和有用策略的第一个实例通过C H键激活。所描述的方法能够在温和条件下选择性地形成C S键,而无需任何配体,氧化剂和芳基/烷基卤化物。
