PtCl2 was found to efficiently catalyze intermolecular additions of propiolate esters with alcohols. The reaction of propiolate esters and alcohols in the presence of PtCl2 gave (E)-vinyl ethers as the major products at 60 °C, whereas alkyl 3,3-dialkoxypropanoates were predominantly obtained when the reaction temperature was set to 80°C. On the other hand, a novel regioselective tetramerization of propiolate esters catalyzed by AuCl3 under mild conditions afforded 1,2,5,6-tetrasubstituted- cyclooctatetraene (1,2,5,6-COT) in moderate yields.

PROBLEM TO BE SOLVED: To provide a method for producing a substituted vinyl ether derivative by ether exchange from a substituted vinyl ether which has an electron-attracting group as a substituent on a double bond carbon atom to cause the binding site to be electron-deficient. SOLUTION: The method for producing a substituted vinyl ether derivative comprises subjecting a substituted vinyl ether, which has at least one electron-attracting group as a substituent on a carbon atom which forms carbon-carbon double bond, to ether exchange reaction with an alcohol or a phenol in the presence of a catalyst containing a compound of the group 9 and/or 10 metal in the periodic table, wherein the compound has a counter anion, and when the anion is protonated, the proton has an ionization constant (pKa) of 0 or less.
