Reaction Conditions

Reaction Steps

60 ml of dimethylformamide and 7.38 g of 2-mercapto-5-(3'-trifluoromethylphenyl)-1,3,4-oxadiazole (m.p. 154°-155° C.) and 0.7 g of potassium hydroxide are stirred in an autoclave. 22 g of tetrafluoroethylene are pressed in, and the reaction mixture is heated for 19 hours at 60° C. (10-12·105Pa). After cooling and release of pressure, the solution is poured into ice-water, the product is taken up in chloroform, the chloroform solution is washed with 1n sodium hydroxide solution, and the solvent is removed in vacuo, affording as reside the title compound in the form of an oil with a refractive index nD22 of 1.4926.
