[70]Fullerene-Fused Lactones: Regioselective Synthesis and Electrochemical Derivatization
{{output}}
[70]Fullerene (C70)-fused five-membered-ring lactones were synthesized via manganese(III) acetate (Mn(OAc)3)- or air-promoted protocols. Under Mn(OAc)3-promoted conditions, three isomers 2a-c were obtained. In contrast, the single isomer 2a was regioselectivel... ...
