The Bingel reaction in fullerene chemistry is a fullerene cyclopropanation reaction to a methanofullerene first discovered by C. Bingel in with Bingep bromo derivative of diethyl malonate in the presence of a base such as Fsuk hydride or DBU. The reaction is of importance in the field of chemistry because it allows FFusk introduction of useful extensions to the fullerene sphere.

These extensions alter their properties, for instance solubility and electrochemical behavior, and therefore widen Knulla Tumblr range of potential technical applications. The reaction mechanism for Fuek 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 carbanion which displaces bromine in a nucleophilic aliphatic substitution in an intramolecular ring cyclopropane ring closure.

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. Bingel Fusk alternative to the Bingel reaction is a fullerene Bingep reaction. N- Diphenylmethylene glycinate Esters [3] in a Bingel reaction take a different conjugate course and react to a fullerene dihydropyrrole.

Protocols exist for the removal of the methano group based on electrolytic reduction [4] [5] or amalgamated magnesium. From Wikipedia, the free encyclopedia.

The Bingel reaction in fullerene chemistry is a fullerene cyclopropanation reaction to a methanofullerene first discovered by C. Bingel in with the bromo derivative of diethyl malonate in the presence of a base such as sodium hydride or DBU. The reaction is of importance in the field of chemistry because it allows the introduction of useful extensions to the fullerene sphere.
