Synthesis of 3′H-cyclopropa[1,9](C60-Ih)[5,6]fullerenes from 2′-aryl-1′,1′-dimethyl-2′,5′-dihydro-1′H-pyrrolo[3′,4′:1,9]-(C60-Ih)[5,6]fulleren-1-ium iodides

Abstract

New 1′,1′-dimethyl-2′,5′-dihydro-1′H-pyrrolo[3′,4′:1,9](C₆₀-I_h)[5,6]fulleren-1-ium iodides containing different aryl groups in position 2 of the pyrrolidine ring have been synthesized. Their reactions with bis-(toluene)chromine afforded the corresponding 3′-aryl-3′H-cyclopropa[1,9](C₆₀-I_h)[5,6]fullerenes.
