Because of the rotation of the … WebThe kinetics of the Bingel reaction with halogenmethyl ketones and C 60 fullerene has been studied in streaming mode by sampling the reaction mixture at different time intervals and separating the components using HPLC. A quantum-chemical simulation of this cyclopropanation process has been carried out with the DFT method.
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 sodium hydride or DBU. The preferred double bonds for this reaction on the … 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. … See more The Bingel reaction is a popular method in fullerene chemistry. The malonate (functionalized with the halide atom) is often obtained See more Protocols exist for the removal of the methano group based on electrolytic reduction or amalgamated magnesium.
