N 2 from a primary alkanediazonium ion predominantly takes place concomitantly with participation of a C-H bond of the neighboring 1-alkyl group to form a nonclassical cationic species with a three-center two-electron bonding, while the loss of N 2 from a secondary alkanediazonium ion occurs spontaneously to form a secondary carbocation. Solvent effects (CHCl 3 vs AcOH) are explained in terms of lower
