An alternative route to [5,6]fullereno-C(60)-I(h)()-[1,9-d]-2'-hydroxycyclohexanone (4a) is presented based on the [4 + 2] cycloaddition of 2,3-bis(trimethylsiloxy)butadiene (3) and [60]fullerene. The oxidation of the primary monoadduct with bromine yield the new [5,6]fullereno-C(60)-I(h)()-[1,9-d]-1',2'-cyclohexanedione (5) which can be isolated as the dimethoxime derivative (9). The diketone 5 constitutes
基于[4 + 2]环加成,给出了[5,6]富勒烯-C(60)-I(h)()-[1,9-d] -2'-羟基环己酮(4a)的替代途径2,3-双(三甲基甲硅烷氧基)丁二烯(3)和[60]富勒烯。初级一加合物被溴氧化生成新的[5,6] fullereno-C(60)-I(h)()-[1,9-d] -1',2'-环己二酮(5)分离为二甲肟衍生物(9)。二酮5构成用于合成不同取代的[5,6]富勒烯-C(60)-I(h)()-[1,9-b] -1',2',3',4的通用反应物'-四氢吩嗪(6a-d)。本文介绍了这些新杂环的分离,表征,可控温度(1)H NMR测量以及紫外可见和荧光研究。
