Reactions of Carbanions of Bis(dialkoxyphosphoryl)bromomethane with Fullerenes C60 and C70.

The reactions of carbanions of bis(dialkoxyphosphoryl)bromomethanes with fullerenes C60 and C70 afforded new bis(dialkoxyphosphoryl)methanofullerenes C60 and C70, respectively, whose structures were established by spectroscopic methods.
