Matrix isolation akd IR spectroscopic study of the pyrolysis products of 2-methyl-3,4-diazapenta-1,3-diene. Cleavage of NN-boud in unsaturated azo compounds
Under verylow-pressurepyrolysis (VLPP) conditions the decomposition of 2-methyl-3,4-diazapenta-1,3-diene proceeds via: (a) homolytic cleavage of CN-bonds with the formation of methyl and 1-methylvinyl radicals (); (b) cleavage of double NN-bond with the formation of N-methyl methyleneimine () and acetonitrile. A mechanism involving decomposition of the intermediate 1,4-diazacyclobutene has been
