Although benzylic and allylic sp3 carbon-nitrogen bonds can be cleaved by certain metals and strong bases, benzylic and allylic amine derivatives have hardly been exploited as useful alkylating agents. For reviews, see: a T. W. Greene, P. G. M. Wuts, Protective Groups in Organic Synthesis, 3rd ed, Wiley: New York, 1999;
