sulfonamidation of primary and secondary benzylic aclohols catalyzed by a 1,2,3,4-tetrafluorophenylboronic acid/oxalic acid co-catalytic system has been examined. The reaction proceeds in mild conditions with readily available starting materials and has been shown to be gram-scalable without significant decrease of yield. Both primary and secondary benzylic alcohols were evaluated and afforded the
已经研究了由 1,2,3,4-四氟苯基硼酸/草酸共催化体系催化的伯和仲苯甲醇的直接磺酰胺化。该反应在温和条件下进行,起始原料易于获得,并且已显示为克级规模,而收率没有显着降低。对伯醇和仲苄醇进行了评估,并以良好到极好的收率提供了所需的磺酰胺产品
