摘要：

By reaction of methanebisphosphonate 9 with NaH/diethyl chlorophosphite and in situ oxidation with atmospheric oxygen the methanetrisphosphonic acid hexaethylester 10 in moderate yields, but in pure form is available. The same product is formed from tetraethyl diazomethane diphosphonate 11 and diethylphosphite in presence of Cu-acetylacetonate. 10 can be transformed using the BTMS/H2O-method to the trisphosphonic acid 13, which is a stable compound.
