Thiazoloquinoxalinium oxide salts [Elektronische Daten] [K. Fedotov, N. Romanov] It was established that the protonation and alkylation of mesoionic thiazolo[3,2-a]quinoxalinium 1-oxides does not take places at the oxide oxygen atom but rather at the nitrogen atom in the 5-position. The π-electron structures of the compounds obtained were studied by the Pariser-Parr-Pople (PPP) method. Plenum Publishing Corporation, 1990 Fedotov K.
