醋酸锰促进的[60]富勒烯与羧酸的自由基反应研究
首发时间:2009-10-12
摘要:在醋酸锰作用下和对二甲氨基吡啶存在下[60]富勒烯与溴乙酸发生一步反应生成了预期的富勒烯内酯衍生物,然而,[60]富勒烯与3-氯丙酸反应产生了一个脱掉一分子HCl的非预期内酯产物。此外,相似反应条件下[60]富勒烯与1-萘乙酸反应给出了对应内酯及1,4-加成两种富勒烯产物。富勒烯内酯及1,4-加成产物可以在适当反应条件下选择性地获得。

Manganese(III) Acetate-Mediated Radical Reaction of [60]Fullerene with Carboxylic Acids
Abstract:The manganese(III) acetate-mediated radical reaction of [60]fullerene with three carboxylic acids was investigated. The reaction of [60]fullerene with bromoacetic acid in the presence of 4-(dimethylamino)pyridine afforded the anticipated fullerene-fused lactone, while the reaction from 3-chloropropionic acid unexpectedly led to the formation of a novel [60]fullerene-fused lactone with the loss of one molecule of HCl. In addition, the reaction with 1-naphthylacetic acid under the similar conditions gave both fullerenyl lactone and fullerenyl 1,4-adduct. Interestingly, the fullerenyl lactone and fullerenyl 1,4-adduct could be selectively obtained by controlling reaction conditions.
