Abstract
A systematic investigation of the photoinduced [6π]-electrocyclization reaction of diphenylamine and N-methyldiphenylamine has been carried out under steady-state and time-resolved conditions in homogeneous (cyclohexane, acetonitrile and methanol) and micellar solutions (sodium dodecyl sulfate -SDS, cetyltrimethylammonium chloride-CTAC and polyethylene glycol monododecyl ether-Brij P35). The photolysis of such compounds in both homogeneous and micro-heterogeneous media afforded the corresponding carbazoles in almost quantitative yield under oxidative conditions. Furthermore, the relative rate of formation of the photoproducts increases when moving from homogeneous media to micellar solution, due to the environmental confined and hydrophobic micellar core as highlighted by 1D and 2D NMR (NOESY and DOSY) spectroscopic analyses.
