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.

The hitherto unexplored class of acylated fullerene compounds has been shown to be excellent C60H2 precursors. Upon a simple treatment with basic Al2O3, they are hydrolyzed quantitatively into C60H2. This key feature led to the development of a new, straightforward protocol for the selective synthesis of the simplest [60]fullerene hydride, C60H2. This protocol may offer an advantageous alternative
