The photochemical version of the Boulton–Katritzky reaction has been studied, examining the behaviour of the arylhydrazones of 3-benzoyl-5-X-1,2,4-oxadiazoles. The effect of several modifications of the substrates structure (the E and/or Z structures of arylhydrazones, the possible presence of substituents in the arylhydrazono moiety, and the nature of substituents at C-5 of the 1,2,4-oxadiazole ring)
研究了Boulton–Katritzky反应的光化学形式,研究了3-苯甲酰基-5-X-1,2,4-恶二唑的芳的行为。对底物结构(芳基hydr的E和/或Z结构,芳基hydr基部分中可能存在取代基以及1,2,4-恶二唑环的C-5处取代基的性质)进行多次修饰的影响对光化学重排过程进行了研究。
