✦ Synopsis
Under very low-pressure pyrolysis (VLPP) conditions the decomposition of 2-methyl-3,4_diazapenta-1,3-diene proceeds via: (a) homolytic cleavage of C-N-bonds with the formation of methyl and I-methylvinyl radicals (1); (b) cleavage of double N=N-bond with the formation of N-methvi methvleneimine (3) and acetonitrile, A mechanism involving lobutene has been decomposition of the-intermediate 1,4-diazacycsuggested for (b).
Azo alkanes are believed to be good starting compounds for thermal and photochemical generation of alkyl radicals:
