Photochemical Behaviour of Some 1,2,4-Oxadiazole Derivatives

Buscemi, Silvestre,Cicero, Maria G.,Vivona, Nicolo,Caronna, Tullio

, p. 1313 - 1316 (2007/10/02)

The photochemical behaviour of some 1,2,4-oxadiazole derivatives in methanol has been studied at 254 nm.On irradiation, 3-amino- (or 3-methylamino-) 5-aryl-1,2,4-oxadiazoles underwent a ring photoisomerization to 1,3,4-oxadiazoles, probably through a 'rin
