Dihydrothiopyran-fused [60]fullerene from hetero-Diels–Alder reaction with thioacrylamide and acyl chloride

Abstract

[60]Fullerene undergoes a smooth irreversible hetero-Diels–Alder reaction with an α,β-unsaturated thiocarbonyl compound, prepared in situ from thioacrylamide and acyl chloride, to give dihydrothiopyran-fused [60]fullerene cycloadducts.
