The method was developed for synthesis of hard-to-reach phosphorylated aldehides with hidden carbonyl group. As compounds with active methylene group triethyl ethers of phosfonacetic acid and diethoxycianomethyl phosfonate were used at the condensation with bromo- and chloroacetals to produce the corresponding acetals. It was found that in the mentioned phosphonates the alkylation by haloid acetal occurs exceptionally on the carbon atom of active methylene group, not touching the nitrile and ester groups. The hydrolysis of obtained phosphorylated acetals led to preparation of phosphorylated aldehydes. It was found that an application of chlorinated acetals led to decreasing the yield of final products. On the basis of obtained aldehydes the corresponding hydrozones were prepared. The latter in the course of reaction undergoes the conversion occurring on the nitrile and ester groups. The high reaction activity of synthesized phosphorylated acetals was used in the further synthesis of different kind of phosphoroganic compounds.  The reaction of phosphorylated aldehydes with hydrazine led to obtaining the nitrogen and phosphor containing organic compounds. The structures of synthesized compounds were studied and proved by IR and NMR spectroscopy methods. Forcitation:                                                                                                                    Ismailov V.M., Yusubov N.N., Sadykhova N.D., Ibragimova G.G., Mamedov I.A.
