The cross-coupling of S-aryl and S-alkyl potassium thiomethyltrifluoroborates with aryl and heteroaryl bromides is reported via photoredox/nickel dual catalysis. The transformation is achieved under mild conditions with commercially available or readily prepared, air stable reagents and affords benzylthioether products in moderate to good yields with good functional group tolerance. A practical and
据报道,通过光氧化还原/镍双重催化,S-芳基和S-烷基硫代甲基三氟硼酸钾与芳基和杂芳基溴化物发生交叉偶联。该转化是在温和的条件下用可商购或易于制备的空气稳定的试剂完成的,并以中等至良好的收率提供了具有良好官能团耐受性的苄基硫醚产品。还报道了一种实用且改进的硫代甲基三氟硼酸钾的合成方法,该方法可提供以前未描述的试剂。
