[摘要]:A variety of benzylic brominations were performed by Using N-bromosuccinimide in (trifluoromethyl)benzene with photochemical activation in the presence of 2.2'-azobisisobutyronitrile, 1,1'-azobis(cyclohexanecarbonitrile), or benzoyl peroxide as the radical initiator. This system provides clean, rapid, and high-yielding reactions with replacement of conventional solvents, such as tetrachloromethane, by less-toxic (trifluoromethyl)benzene. |
