There is provided a sulfur-containing fluorinated alpha , beta -unsaturated carbonyl compound expressed by a general formula, R min -@-CF=CF-S-R<2> wherein R<1> and R<2> are independently an aliphatic or aromatic group with or without a substituent or substituents. Further, a process of manufacturing the above compound wherein a halide of fluorinated carbonyl compound expressed by the general formula, R<1>-@-CHF-CF2X wherein R<1> is an aliphatic or aromatic group with or whithout a substituent or substituents and X is a halogen atom, is reacted with a mercaptan expressed by a general formula, R<2>-SH wherein R<2> is an aliphatic or aromatic group with or without a substituent or substituents, to produce a sulfur-containing fluorinated carbonyl compound expressed by a general formula, R<1>-@-CHF-CF2-S-R<2> wherein R<1> and R<2> are the same as those of the starting materials, and this sulfur-containing carbonyl compound is converted, by the elimination of hydrogen fluoride, to a sulfur-containing fluorinated unsaturated carbonyl compound expressed by a general formula, R<1>-@-CF=CF-S-R<2> wherein R<1> and R<2> are the same as those of the starting materials. |
