Cover Feature: Microwave‐Assisted 1,3‐Dipolar Cycloaddition of Azomethine Ylides to [60]Fullerene: Thermodynamic Control of Bis‐Addition with Ionic Liquids Additives (Eur. J. Org. Chem. 25/2021)

The Cover Feature shows a kaleidoscopic vision of the frontier empty orbitals of [60]fulleropyrrolidine embracing diverse [6,6] bonds, which poses a severe regioselectivity challenge for further ylide cycloaddition, resulting in a multitude of polyfunctionalization products. A combined kinetic and mechanistic study is reported to interrogate the thermodynamic drivers, leading to stable fulleropyrrolidine bis-adducts, using MW-assisted heating and ionic liquids additives.
