3′H-Cyclopropa[1,9](C60-I h )[5,6]fullerene-3′-carboxylic acid can be synthesized in a good yield by cyclopropanation of fullerene C60 with 2-(dimethyl-λ4-sulfanylidene)acetates provided that the ester residue is readily hydrolyzable in acid medium.

An efficient catalytic method of the cycloaddition to C60 fullerene of the diazoacetates, containing substituents of diverse structures in ester groups, in the presence of a Pd-based three-component catalyst was developed. An influence of nature and the structure of substituent in the ester group on the activity of diazoacetates in the reaction with C60 was studied. Yields of respective cycloadducts were determined.
