FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing 4-allyl-2-methoxyphenoxy-beta-carboxyethenylphenoxy-cyclotriphosphazenes, which can be used in dentistry to produce filling compositions with improved operational properties. In the disclosed method, 4-allyl-2-methoxyphenoxy-beta-carboxyethenylphenoxy-cyclotriphosphazenes are obtained by successive substitution of chlorine atoms in chlorocyclophosphazenes with 4-allyl-2-methoxyphenoxy groups by reaction with 4-allyl-2-methoxyphenol and further substitution of residual chlorine atoms with para- or meta-hydroxybasedaldehydes or salicylic aldehyde or a mixture of said aldehydes and subsequent conversion of aldehyde groups to beta-carboxyethenyl by reaction with malonic acid.
EFFECT: novel efficient method of producing 4-allyl-2-methoxyphenoxy-beta-carboxyethenylphenoxy-cyclotriphosphazenes.
