2,5-环己二烯酮类的固相光化学(Ⅱ)

Solid-State Photochemistry of 2,5-Cyclohexadienones(Ⅱ)

本文报道了2,4,6-三叔丁基-4-甲氧基-2,5-环己二烯酮的固相光化学反应,所得三种产物的比率随温度而变化,而液相光化学反应与温度无关。用带有NaNO_(2)滤色液的光照射该化合物,几乎得到100%的列米酮。在列米酮中加入少量萘的固相光化学反应所得产物的比率随萘量而变化。

Photochemical reaction of 2,4,6-tri-t-butyl-4-methoxy-2,5-cyclohexadienone in the solid-state has been investigated.Photoketone,photophenol,lumiketone were obtained.The ratios of products varied with temperature.In solution,the ratio was not effected by temperature.Irradiation of crystals of 2,4,6-tri-t-butyl-4-methoxy-2,5-cyclohexadienone with filter of solution of NaNO_(2),the lumiketone was obtained almost quantitative yield.If the mixture of lumiketone containing a small amount of naphthalene is irradiated,the ratios of products varied with amount of naphthalene.
