[Structure: see text] 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.
[结构:见正文]热处理在炔烃部分末端碳上带有烷基的1,6-富勒烯炔通过涉及分子内烯过程的反应机理定量地导致新的丙二烯。该反应结果与最近发现的通过[2 + 2]环化机理形成环丁烯衍生物的游离末端炔烃相反。
