C-Phosphorylation of Azoles with Trivalent Phosphorus Halides

Abstract Simple method of C-phosphorylation of azoles by trivalent phosphorus halides in the pyridine solution have been developed. Hetaryldihalogen, dihetarylhalogen-, trihetarylphosphines, which were transformed into new types of P(III) and P(IV) derivatives, have been synthesized. Features of their reaction ability stipulated by the influence of hetaryl residues are found.

C-Phosphorylation of Formamidines

C-Phosphorylation of formamidines by trivalent phosphorus halides was researched. Direction of the phosphorylation depends on nature of substituents at the amidine nitrogens. C-Phosphorylated products was shown to be of valuable possibilities to construct phosphoruscontaining heterocycles

C-Acylation of Electron-Excess Heterocycles by Isocyanatophosphoric Acid Dichlorides

Abstract Isocyanatophosphoric acid dichlondes was used for introduction of phosphorus-containing groups at electron-excess heterocycles. Hetaryl containing dichlorophosphates, convenient starting material for synthesis for wide set of derivatives, were prepared by C-acylation with this reagent.
