Base-catalysed oxidative [3 + 2]cycloaddition reaction of [60]fullerene with β-dicarbonyl compounds
Abstract
The ambiphilic nature of β-keto esters and β-diketones allows cycloaddition to C60 in the presence of piperidine to give dihydrofuran-fused C60 derivatives via oxidative cyclization complimentary to the concerted process.
