3-Sulfolene-3,4-dicarboxylates effective for generation of bis(methylene)butanedioates were applied to [4+2] cycloaddition reaction of C60 to give fullerocyclohexenedicarboxylates, among which a t-butyl ester was hydrolyzed to a dicarboxylic acid derivative, useful for further conversion into its anhydride and half-esters.
对C 60的[4 + 2]环加成反应应用有效生成双(亚甲基)丁二酸酯的3-环-3,4-二羧酸酯,得到全环己烯二羧酸酯,其中叔丁基酯水解为二羧酸衍生物,用于进一步转化为其酸酐和半酯。
