Pyrolytic study of 2-(2-Azidoethyl)-1H-indole and 2-Azido-1-(1H-indol-2-yl)ethanoneChou, Wei-zhen 05 August 2004 (has links)
Flash vacuum pyrolysis (FVP) of 2-(2-azidoethyl)-1H-indole, via a nitrene intermediate, gave two products, 2-methyl-1H-indole and quinoline. However, under the same route, FVP of 2-azido-1-(1H-indol-2-yl)ethanone produced indole, 1-(1H-indol-2-yl)ethanone, (1H-indol-2-yl)-[4-(1H-indol-2-yl)-1H-imidazol-2-yl]ethanone and it¡¦s isomer.

Ptrolytic Study of 2-(azidoethyl)pyridine and 1-methyl-2- (2-azidoethyl) pyrroleChen, Li-Hui 04 July 2002 (has links)
Flash vacuum pyrolysis(FVP) of 2-(azidoethyl)pyridine, via a nitrene
intermediate, gave two products, a dimer (1,2-di(2-pyridinyl)-ethane) and a trimer
(3,5-di(2-pyridyl)-pyridine). However by the same route, FVP of 1-methyl-2-
(2-azidoethyl) pyrrole produced only a dimer (1,2-di(1-methylpyrrol-2-yl)ethane).
