The Thermolysis of Polyazapentadienes. Part 4. Formation of Indoles and Quinoxalines from 5-(2,6-Disubstituted phenyl)-1,2,5-triazapentadienes and Related Compounds

McNab, Hamish

, p. 377 - 380 (2007/10/02)

7-Methylindole and 5-substituted quinoxalines are the principal cyclised products from the qas-phase thermolyses of the hydrazones (2) and (5) and the oxime ester (7).Both heterocyclic systems arise by competitive decomposition of the spirodienyl radical, e.g. (18), the indole by loss of MeCN and a hydrogen atom, and the quinoxalines by loss of a methyl radical.
