N2  - Gas-phase pyrolysis of cyclopentanone and cyclohexanone azines results in the formation of iminyl radicals. These undergo ring cleavage to the &#969;-cyanoalkyl radicals, which stabilize, by internal hydrogen-atom transfer, to the corresponding &#945;-cyanoalkyl radicals. Fragmentation of the latter yields acrylonitrile and alkyl radicals, which can recombine with the &#945;-cyanoalkyl radicals to form &#945;-alkylated nitriles. The mechanisms involved are discussed with reference to isotopic labellingstudies.
