Palladium-catalyzed synthesis of [60]fullerene-fused furochromenones and further electrochemical functionalization†
Abstract
An efficient synthesis of [60]fullerene-fused furochromenones has been developed by the palladium-catalyzed heteroannulation of [60]fullerene with 4-hydroxycoumarins. The formed [60]fullerene-fused furochromenones can be further derivatized via an electrochemical method to synthesize 1,2,3,4-adducts in high yields.
