Abstract

We have worked out a selective and efficient mode of the synthesis of substituted and unsubstituted piperazine-containing mono-adducts of the C₆₀ fullerene. It is based on the C₆₀ reaction with piperazine, 2-methylpiperazine, and 2-oxopiperazine under air, room temperature and ultrasonication. The intermediate of the sonochemical reaction is radical anion C₆₀^•–, which was detected with EPR (g = 1.9968, ΔH = 5.9 G). This intermediate is generated due to one-electron transfer from piperazine to the C₆₀ molecule.

C60 富勒烯的含哌嗪加合物的声化学合成

摘要

我们已经找到了一种选择性和有效的合成 C ₆₀富勒烯的含取代和未取代哌嗪的单加合物的模式。它基于在空气、室温和超声处理下与哌嗪、2-甲基哌嗪和 2-氧代哌嗪的 C ₆₀反应。声化学反应的中间体是自由基阴离子 C ₆₀ ^•–，用 EPR (g = 1.9968, ΔH = 5.9 G) 检测到。该中间体是由于从哌嗪到 C ₆₀分子的单电子转移而产生的。
