摘要：
The invention relates to a method for the coupling production of acetic acid or propionic acid reaction products and a vinyl ester of formula R-C(O)O-CH = CH2
by a transvinylation reaction of a carboxylic acid of formula R-C(O)OH with a transvinylation reagent of formula R
1 -C(O)O-CH = CH
2 wherein R represents an aliphatic, cycloaliphatic or aromatic radical and R
1 is methyl or ethyl and the transvinylation reaction is continuously carried out without removing a reaction partner in the presence of a transition metal catalyst containing at least one transition metal selected from the group comprising ruthenium, osmium, rhodium, iridium, palladium and platinum, the obtained reaction mixture being separated from its components, the vinyl ester of formula R-C(O)O-CH = CH2 and the carboxylic acid of formula R
1 -C(O)-OH being separated and the thus obtained carboxylic acid R
1 -C(O)-OH being converted into a derivative of formula R
1 -C(O)-X, R
1 -CH
2 -OH or R
6 -C(O)-OH.
