Flash vacuum pyrolysis of phenylazonaphthols and nitrosonaphthols at 700°C and 0.02Torr yielded quinoline, isoquinoline, indene and naphthols (and aniline only from the phenylazo derivatives). Similar FVP of p-nitroso and p-phenylazophenol gave pyridine.
Oxidative degradation of organic photochromes

Photo-oxidation of some representative spiropyrans and spiro-oxazines does not seem to involve singlet oxygen O2(1Δg). The photochromes rather behave, in the spiro and merocyanine form, as O2(1Δg) quenchers. Only a methoxy-nitro benzopyran derivative was found to promote formation of singlet oxygen. Superoxide anion O2 is likely the activated oxygen species responsible for their oxidative photodegradation.
