Abstract
A series of novel transformations of 60fullerene derivatives were found, starting from methano60fullerenes with an electron-donating group on the methano-bridge carbon. Aminomethano60fullerenes, in situ generated by the treatment of their trifluoromethanesulfonic acid salts with a base, were readily converted into 1-acyl-1,2-dihydro60fullerenes via the ring opening of the cyclopropane moiety. The aldehyde/ketones thus obtained were easily hydrolyzed to give 1,2-dihydro60fullerene in the presence of hydroxide anions. [ABSTRACT FROM AUTHOR]
