[反应：在C_（60）与1，1，2，2-四（2，6-二乙基苯基）-1，2-二锗烷（1）的光化学双甲锗化反应中，首次以高产率得到环加合物（2）。光谱分析和理论研究证实2（具有C1对称性）是1，4-环加成反应的产物。控制实验和激光闪光光解实验表明，激基复合物中间体是负责形成2。用微分脉冲伏安法研究了2的氧化还原性质。
[reaction: see text]In the photochemical bis-germylation of C60 with 1,1,2,2-tetrakis(2,6-diethylphenyl)-1,2-digermirane (1), a cycloadduct (2) is obtained in high yield for the first time. Spectroscopic analysis and theoretical investigation confirm that 2 (which has C1 symmetry) results from 1,4-cycloaddition. Control experiments and laser flash photolysis experiments suggest that an exciplex intermediate is responsible for the formation of 2. The redox properties of 2 were examined by differential pulse voltammetry.
