Palladium-Catalyzed Benzylic C−H Insertion of 2-Substituted N-Iminopyridinium Ylides

Palladium-catalyzed direct benzylic C-H arylation of 2-alkyl substituted N-iminopyridinium ylides is described. The insertion can be conducted with several electron-poor and electron-rich aryl chlorides in good yields. This work adds to the few examples of sp3 C-H insertions that have been reported so far.
