On the Photodegradation of 3,3-Diphenyl-[3H]-Naphtho[2,1-b]Pyrane in Solution: Mechanistic Aspect

Abstract

The present contribution is devoted to the investigation of the oxidative degradation of the 3,3-diphenyl-[3H]-naphtho[2,1-b]pyrane in toluenic solution. In order to propose some mechanisms concerning these degradation processes, we have identified the photoproducts by mean of coupled technics (GC-FID, HPLC-DAD, GC-MS). In those conditions, we have observed the production of benzophenone, β-phenylcinnamaldehyde, 2-hydroxy-1-naphthaldehyde along with an unidentified product detected by GC-MS (m/z = 256 g.Mol⁻¹).
