れたことは驚くべき効果である。(■') (m) (1') As a result of further study on the above reaction, the present inventors found that if a metal or metal ion is used as an additive during the dehydrohalogenation reaction, the amount used in a catalytic amount can be reduced. The inventors have now discovered that the above reaction can proceed under milder conditions and that highly purified thiophenedicarboxylic acid diester can be obtained in good yield, leading to the present invention. The dehydrohalogenation reaction can be carried out simply by heating, but in this case, the reaction is
Since it must be carried out at a high temperature of 50° C., tar formation occurs due to thermal history, and a decrease in yield cannot be avoided. However, it is a surprising effect that the addition of a catalytic amount of an inexpensive metal or metal ion according to the present invention resulted in yields as shown in the Examples below.
