The reaction of C70 with CH2(PO3Et2)2 or CH2(PO3Et2)CN in the presence of NaH has been reinvestigated. The reaction of C70 with the former phosphonate affords five products. Products 1–3 have molecular structures C70>CH(PO3Et2), whereas products 4 and 5 have molecular structures C70>C(PO3Et2)2. In contrast, only one product 6, with a molecular structure C70>C(PO3Et2)CN, could be isolated from the reaction
