Abstract New triazolo[4,5-d]pyrimidine and pyrazolo[3,4-d]pyrimidine derivatives of aminomethyl-and aminomethyloxymethyl dimethylphosphine oxides 8–14 as well as of esters of (aminomethane) phosphonic acid 18–20 were synthesized. The structure of the compounds prepared was confirmed by means of elemend analysis, IR, 1H- and 31P(1H)-NMR spectroscopy. Tertiary phosphine oxides 8, 9 and 12 as well as
