Synthesis of Pentamethyl-monohydro[60]fullerene C60Me5H and Its Use as Cyclopentadienyl-Type Ligand Precursor

Abstract
Pentamethyl-monohydro[60]fullerene C60Me5H has been synthesized through five-fold addition of methylcopper reagent to C60. The anion C60Me5 generated by deprotonation of C60Me5H forms organometallic complexes with K+ and Tl+ ions with stronger metal-carbon interaction than that in the corresponding pentaphenylated ligand C60Ph5.
