内嵌金属富勒烯La @ C_（82）与3-氯-3-苯基二氮杂环丙烷（3）的光化学反应生成苯基氯卡宾（：CClPh）衍生物。紫外-可见-近红外光谱和电子自旋共振光谱分析及理论计算表明，该单加合物是一对带有卡宾取代基的立体异构体，卡宾加成反应区域选择性地发生在具有高电荷密度和高局域应变的C82笼上.
The photochemical reaction of an endohedral metalofullerene La@C82 with 3-chloro-3-phenydiazirine (3) affords the monoadduct as a phenylchlorocarbene (:CClPh) derivative. Spectroscopic analyses of UV-vis-near infrared and electron spin resonance and the theoretical calculations reveal that this monoadduct is a pair of stereoisomers with carbene substituents, and the carbene addition occurs regioselectively to the carbons having a high charge density and a high local strain of the C82 cage.
