在1，6-富勒烯的末端碳上含有烷基的1，6-富勒烯的热处理通过分子内烯过程的反应机理定量地导致新的烯烃。这一反应结果与最近发现的自由末端炔烃相反，后者通过[2+2]环化机制形成环丁烯衍生物。
Thermal treatment of 1,6- fullerenynes bearing an alkyl group on the terminal carbon of the alkyne moiety leads quantitatively to new allenes through a reaction mechanism involving an intramolecular ene process. This reaction outcome is in contrast to that recently found for free terminal alkynes which form cyclobutene derivatives through a [ 2+ 2] cyclization mechanism.
