Abstract
A four-component reaction of aryldiazonium tetrafluoroborates, sulfur dioxide, 1,2-dibromoethane, and hydrazines under metal-free conditions is described, providing a novel and efficient approach to 2-arylsulfonyl hydrazones. This transformation proceeds smoothly via insertion of sulfur dioxide under mild conditions with good functional group tolerance.
摘要
描述了在无金属条件下芳基四氟硼酸重氮盐、二氧化硫、1,2-二溴乙烷和肼的四组分反应，为制备2-芳基磺酰腙提供了一种新颖有效的方法。该转化通过在温和条件下插入二氧化硫顺利进行，具有良好的官能团耐受性。
