bond formation to an aryl ring is reported. The reactions are conducted under mild conditions and afford tetralin derivatives bearing difluoromethyl as well as other fluoroalkyl groups in good to high yields. In addition, the study indicates that 6-exo radical cyclization of an alkyl radical to a phenyl ring is faster than the respective 5-exo radical cyclization. A computational study provides insights
据报道,第一个例子是光氧化还原催化未活化烯烃的二
氟甲基化,并与形成芳基环的C-C键结合。该反应在温和的条件下进行,并以良好或高收率得到带有二
氟甲基以及其他
氟代烷基的四氢
萘衍
生物。另外,该研究表明,烷基至苯环的6-exo自由基环化比相应的5-exo自由基环化更快。计算研究为实验结果提供了见识。
