Bingel hirsch reaction

The Bingel reaction is a popular method in fullerene chemistry. The malonate (functionalized with the halide atom) is often obtained in situ in a mixture of base and tetrabromomethane or iodine. The reaction is also known to take place with the ester groups replaced by alkyne groups in dialkynylmethanofullerenes. … See more The Bingel reaction in fullerene chemistry is a fullerene cyclopropanation reaction to a methanofullerene first discovered by C. Bingel in 1993 with the bromo derivative of diethyl malonate in the presence of a base such as See more The reaction mechanism for this reaction is as follows: a base abstracts the acidic malonate proton generating a carbanion or enolate which reacts with the electron deficient fullerene double bond in a nucleophilic addition. This in turn generates a … See more Protocols exist for the removal of the methano group based on electrolytic reduction or amalgamated magnesium.
