Significance

The authors report a two-step re­gioselective synthesis of 1,4-di(organo)[60]fulle-renes. In the first step, DMF-assisted monoaddition of silylmethyl Grignard reagent to [60]fulle-renes produces (organo)(hydro)[60]fullerenes. Deprotonation and alkylation in the second step generates di(organo)[60]fullerenes with various functional groups, whose crystal structures, ­electrochemical and thermal properties have been studied.
