FIELD: organic chemistry. SUBSTANCE: the product: a Brensted acid vinyl derivative, purity is 99% Reagent 1: a Brensted acid vinyl derivative selected from the group consisting of vinyl esters of saturated or unsaturated carboxylic acid. Reagent 2: the other Brensted acid. Reaction conditions: in the presence of a ruthenium compound as a catalyst at its concentration of from 30,000 to 0.23 ppm based on the weight of a liquid phase reaction mixture. The Brensted acid to ruthenium molar ratio is maintained at 0.9 to 1 at a temperature of from 75 to 259 C and at a pressure of from 10 to 2644.8 mm Hg. EFFECT: more efficient transvinylation process. 12 cl, 4 tbl
