12difluoroethylene

1,2-Difluoroethylene is a chemical compound with the formula C2H2F2. It is a fluorinated alkene, meaning it contains a carbon-carbon double bond and fluorine atoms. There are three possible stereoisomers of 1,2-difluoroethylene: cis-1,2-difluoroethylene, trans-1,2-difluoroethylene, and a less stable tautomeric form. The cis and trans isomers are geometric isomers, differing in the spatial arrangement of the fluorine atoms around the double bond. In the cis isomer, the fluorine atoms are on the same side of the double bond, while in the trans isomer, they are on opposite sides. Both cis and trans isomers are colorless gases at room temperature. They are typically synthesized through dehydrohalogenation reactions of fluorinated ethanes. These compounds can undergo addition reactions characteristic of alkenes, with the fluorine atoms influencing the reactivity and regioselectivity of these reactions. 1,2-Difluoroethylene and its isomers have found applications as monomers in the production of specialized fluoropolymers, which exhibit unique properties such as chemical resistance and thermal stability. They can also serve as intermediates in the synthesis of other organofluorine compounds. Due to the presence of fluorine, these molecules can have significant environmental and safety considerations that require careful handling and disposal.
