Gas‐phase pyrolysis of N‐arylidine‐N′‐pyrimidin‐2‐yl‐hydrazine derivatives 1a, 1b, 1c, 1d, 1e gave the corresponding arylnitriles 2a, 2b, 2c, 2d, 2e, 2‐aminopyrimidine 3, 3‐phenyl‐1,2,4‐triazolo[4,3‐a]pyrimidines 4, 2‐phenyl‐1,2,4‐triazolo[1,5‐a]pyrimidines 5, 2,4,5‐triphenyl‐1H‐imidazole 6, and 2,3‐diphenylquinoline 7. The analyses of the reaction products are reported and used to elucidate the mechanism
的气相热解Ñ -arylidine- N' -嘧啶-2-基-肼衍生物1A,1B,1C,1D,1E,得到相应的arylnitriles图2a,图2b,图2c,2d中,2E,2-氨基嘧啶3,3-苯基-1,2,4-三唑并[4,3一]嘧啶4,2-苯基-1,2,4-三唑并[1,5-一个]嘧啶5,2,4,5-三苯基-1- ħ咪唑6和2,3-二苯基喹啉7。报告了反应产物的分析,并用于阐明热解过程的机理。
