2-Methyl-3-oxo-indolin-1-oxyl 10 with trifluoroacetic acid gives the disproportionation products 11 and 12.With dry HCl or HBr it undergoes halogenation and deoxygenation and yield halogenated indoxyls 13a-c and 14a-c, and with HI it undergoes deoxygenation to indoxyl 11 or reduction to hydroxylamine 15, depending on the reaction solvent.A deoxygenation mechanism is proposed on the basis of experimental evidence.
