Abstract

tert-Butylperoxy radicals generated by TBHP and Ru(PPh3)3Cl2 or other catalysts adds to C60 and C70 to form stable multiadducts, C60(O)(OOtBu)4 and C70(OOtBu)10. The four tert-butylperoxy groups in the C60 mixed peroxide are located around a pentagon, and the epoxy O occupies the remaining 6,6-bond connected to the same pentagon. The C70 decaadduct shows an unprecedented C2 symmetry with the 10 tert-butylperoxy groups added around the central part of C70 by consecutive 1,4-addition. The compounds are fully characterized by spectroscopic data.

摘要

由叔丁基过氧化氢（TBHP）和二氯三（三苯基膦）钌（Ru(PPh3)3Cl2）或其他催化剂产生的叔丁基过氧自由基加成到C60和C70上，形成稳定的多加合物C60(O)(OOtBu)4和C70(OOtBu)10。C60混合过氧化物中的四个叔丁基过氧基团位于一个五边形周围，环氧基O占据与同一五边形相连的剩余6,6-键。C70十加合物呈现出前所未有的C2对称性，10个叔丁基过氧基团通过连续的1,4-加成添加到C70的中心部分周围。这些化合物通过光谱数据得到了充分表征。
