The structures of products formed in reactions of tert -butylated o -quinones with alkyl radicals were determined by 1H and 13C NMR and two-dimensional 1H-1H NOESY spectroscopy, and also by gas chromatography-mass spectrometry. The major products formed upon γ-irradiation of deaerated solutions of 4- tert -butyl-1,2-benzoquinone and 3,5-di- tert -butyl-1,2-benzoquinone in cyclohexane are monoalkyl
通过1 H和13 C NMR和二维1 H - 1 H NOESY光谱,以及通过气相色谱-质谱法确定 叔丁基 化 邻 醌与烷基反应形成的产物的结构 。在4-脱气溶液γ-照射形成的主要产品 叔 丁基-1,2-苯醌和3,5-二- 叔 在环己烷-丁基-1,2-苯醌是单烷基醚和除了产品C = C键。在4- 叔 的情况下 -丁基-1,2-苯醌,这些是混合的OC和CC烷基化的产物;通过将环己基基团加到3,5- 二叔 丁基-1,2-苯醌中的C = C键上形成的加合物 得到不对称二聚体,其结构已通过单晶X射线衍射证明。
