迄今未开发的一类酰化富勒烯化合物已被证明是出色的C 60 H 2前体。在用碱性Al 2 O 3进行简单处理后,它们被定量水解为C 60 H 2。这一关键特征导致开发了一种新的,直接的方案,用于选择性合成最简单的[60]富勒烯氢化物C 60 H 2。该协议可以为先前已知的C 60 H 2合成方法提供有利的替代方法,从而可以快速获得C 60 H 2。 收率高,纯度高,无需繁琐的分离过程。
Ring-Opening Reaction of Cyclopropanated [60]Fullerenes: Unexpected Transformation of Methano[60]fullerenes Having an Electron-Donating Group on the Methano-Bridge Carbon
摘要:
A series of novel transformations of [60] fullerene derivatives were found, starting from methano[60] fullerenes with an electron-donating group on the methano-bridge carbon. Aminomethano[60]fullerenes, in situ generated by the treatment of their trifluoromethanesulfonic acid salts with a base, were readily converted into 1-acyl-1,2-dihydro[60] fullerenes via the ring opening of the cyclopropane moiety. The aldehyde/ ketones thus obtained were easily hydrolyzed to give 1,2-dihydro[60] fullerene in the presence of hydroxide anions.

A reaction of bis(arene)chromium complexes with [60]fullerene derivatives leads to ionradical bis(arene)chromium [60]fullerides. Bis(1,2,4,5-tetramethylbenzene)chromium [70]fulleride was synthesized similarly. The compounds obtained were characterized by spectroscopic methods, their thermal decomposition was studied and thermal stability of their dimers was evaluated.
