The effect of 4-oxy and 4,5-dioxy substituents on the photochemical conversion of 2-methylbenzaldehydes to o-quinodimethanes (o-QDMs) has been studied. The presence of a 4-methoxy, or a 4 and 5-methoxy substituent prevented the photochemical formation of the o-QDM whereas 4-acetoxy and 4,5-diacetoxy-2-methylbenzaldehyde and the corresponding mesylates and tosylates were successfully converted to the
研究了4-氧基和4,5-二氧基取代基对2-甲基苯甲醛向邻喹啉二甲烷(o-QDMs)的光化学转化的影响。4-甲氧基或4和5-甲氧基取代基的存在阻止了o-QDM的光化学形成,而4-乙酰氧基和4,5-二乙酰氧基-2-甲基苯甲醛以及相应的甲磺酸酯和甲苯磺酸酯则成功转化为o-QDM。
