Abstract

A new, one step functionalization of C with lactones has been developed. This photochemical approach utilizes a variety of lactonyl radicals deriving from lactones through a hydrogen atom abstraction process mediated by tetrabutylammonium decatungstate [(BuN)WO]. This reaction provides access to a previously unknown class of materials, namely 1-lactonyl-2-hydro[60]fullerenes. A mechanism for this new reaction has been proposed based mainly on the structure of reaction products and deuterium-incorporated experiments.

摘要

已经开发出了一种将 C 与内酯进行一步官能化的新方法。这种光化学方法利用了通过四丁基铵十钨酸盐[(BuN)WO]介导的氢原子提取过程从内酯中衍生出的各种内酯基自由基。该反应提供了一种以前未知的材料，即 1-内酯基-2-氢[60]富勒烯。根据反应产物的结构和氘掺入实验，提出了这种新反应的机理。
