Methanofullerenes from Cycloaddition to C60Author(s): Peter Allen*
The most prevalent method of fullerene core functionalization is (2+1) cycloaddition. The most promising of them are those that lead to methanofullerenes. They are created via the thermal addition of diazo compounds and the Bingel process of nucleophilic cyclopropanation. Discussion is held regarding the main cyclopropanating agents employed in the synthesis of mono-substituted methanofullerenes, ideal circumstances and the mechanism of the (2+1) cycloaddition, as well as the functional use of the target products.
The fullerene core is now being functionalized by scientists using high selectivity and yield technologies. With the electron deficient C60 radical inclusion nucleophilic addition, and cycloaddition may all be accomplished fast.
