Abstract

PURPOSE: To prepare the tile compound easily in high yield, by reacting dialkoxycarbonyl ketene mercaptal dialkali salt with cis-1,2-dihaloethylene in a polar aprotic solvent.
CONSTITUTION: The compound I is prepared by reacting dialkoxycarbonylketene mercaptal dialkali salt II (R, R' is lower alkyl; M is alkali metal) with cis-1,2- dihalo-ethylene III (x is halogen) in a polar aprotic solvent (e.g. dimethylsulfoxide, dimethylformamide, diethylformamide, etc.) at a temperature between room temp. and 100°C (pref. 50-80°C).
USE: Agricultural fungicide and medicine.
