A fullerene C 60 Process for the preparation of a negative ion intermediate

Abstract

This invention provides a fullerene C 60 A method for preparing a negative ion intermediate. The fullerene C0 60 The preparation method of an anionic intermediate includes: Step 1: adding o-dichlorobenzene solvent to a reaction flask, heating in an oil bath and purging with an inert gas for protection; Step 2: sequentially adding fullerene C to the reaction flask. 60 A diol solution of tetrabutylammonium hydroxide (TBAOH) reacts for 30-60 minutes to yield fullerene C. 60 A negative ion intermediate. Simultaneously, a method for preparing a fullerene derivative is provided, utilizing the aforementioned fullerene C... 60 The method for preparing fullerene derivatives from an anionic intermediate further includes step three: adding anionic intermediate to the fullerene C 60 An electrophilic reagent is added to an anionic intermediate, and the reaction is carried out at 60℃~120℃ for 1h~3h. After the reaction is completed, the reaction solution is evaporated and purified to obtain fullerene derivatives. Both preparation methods are simple to operate, green and non-toxic, safe and easy to control, efficient and highly selective.
