Under very low-pressure pyrolysis (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
在极低压热解(VLPP)条件下,通过以下方式进行2-甲基-3,4-二氮杂戊-1,3-二烯的分解:(a)CN键的均相裂解,形成甲基和1-甲基乙烯基(); (b)裂解双NN键,形成N-甲基亚甲基亚胺()和乙腈。对于(b),已经提出了涉及分解中间的1,4-二氮杂环丁烯的机理。
