Phenol undergoes thermal 2,5-cycloaddition of N-phenylmaleimide to give endo- and exo-bicyclo-octenones (3) and (4) respectively, and a homopolymer of the maleimide; use of N-(p-methoxyphenyl)maleimide minimizes polymer formation, and gives a combined cycloadduct yield of 60% in the case of p-cresol.
苯酚经历N-苯基马来酰亚胺的热2,5-环加成反应,分别得到内-和外-双环辛烯酮(3)和(4),以及马来酰亚胺的均聚物。使用N-(对甲氧基苯基)马来酰亚胺可最大程度地减少聚合物的形成,在对甲酚的情况下,环加合物的总收率为60%。
