Flash vacuum pyrolysis of aromatic oximes.

Abstract

Flash vacuum pyrolysis (FVP) of benzaldoximes and aryl ketoximes afforded nitriles and additional aromatic compounds which were presumably generated from intermediary iminyl radicals. The FVP also gave benzoxazoles, which were presumably formed from iminoxyl radicals. Benzyl ketoximes afforded indoles together with fragmentation products of the iminyl radicals.
