New one-pot method for the synthesis of pyrrolidinofullerenes

The reaction of fullerene C 60 with isocyanoacetates and EtMgBr in the presence of stoichiometric amounts of Ti(Oi-Pr) 4 was studied for the first time. Unlike esters and nitriles of carboxylic acids and isonitriles, isocyanoacetates were found to react with C 60 under the developed conditions to gi...

Zusammenfassung:The reaction of fullerene C 60 with isocyanoacetates and EtMgBr in the presence of stoichiometric amounts of Ti(Oi-Pr) 4 was studied for the first time. Unlike esters and nitriles of carboxylic acids and isonitriles, isocyanoacetates were found to react with C 60 under the developed conditions to give N -unsubstituted pyrrolidinofullerenes. The electrochemical reduction of the C 60 derivatives we synthesized was found to proceed less easily than that of C 60 but more easily than that of unsubstituted pyrrolidinofullerenes.
