PHOSPHORUS YLIDES, METHOD FOR THEIR PREPARING AND INTERMEDIATE COMPOUNDS

摘要

FIELD: organophosphorus compounds. SUBSTANCE: invention relates to novel phosphorus ylides of the formula (I): where R₁, R₂, R₃ represent amino-group R'R''N where R' and R'' represent C₁-C₆-alkyl; R₄ represents H, Me; R₅ represents polymeric carrier of polystyrene type of the formula (S): where n, n' and m are whole numbers = 1 or more. Compounds of the formula (I) can be used as slightly nucleophilic strong bases. Invention describes also intermediate compounds of the formula: where R¹-R⁵ mean above indicated values; Y^⊖ means anion. EFFECT: improved preparing method, valuable chemical properties of compounds. 4 cl, 1 tbl, 9 ex
