Transition-metal mediated activation of inert chemical bonds is an ongoing topic in homogeneous catalysis.In view of the abundance and accessibility of alkylarenes and benzylamines,the use of them as benzyl source in catalytic benzylation reac-tions via benzylic C-H and C-N bond activation is highly desirable.Indeed,compared with the traditional approaches with benzyl halide as the substrates,benzylation reactions via C-H and C-N bond cleavage provide more efficient,at-om-economic strategies to access myriads of synthetically important molecules.In this account,our group\'s efforts on catalytic benzylation reactions via directed C-H activation,nondirected C-H activation and C-N bond activation are summarized.
