Methano[60]fullerenephosphonic acid (5) and methano[60]fullerene diphosphonic acid (8) have been synthetized through the thermal addition of dimethyl diazomethylphosphonate to C-60 and the Bingel-type reaction of tetramethyl bromomethylene-diphosphonate with C-60, in the presence of DBU, respectively. Hydrolysis of the phosphonic esters thus obtained afforded the corresponding acids.

Abstract
Methano[60]fullerenephosphonic acid (5) and methano[60]fullerene diphosphonic acid (8) have been synthetized through the thermal addition of dimethyl diazomethylphosphonate to C-60 and the Bingel-type reaction of tetramethyl bromomethylene-diphosphonate with C-60, in the presence of DBU, respectively. Hydrolysis of the phosphonic esters thus obtained afforded the corresponding acids.File in questo prodotto:
