  • Patent number: 11725071
    Abstract: Copolymers of one or more halogenated olefins and one or more halogenated co-monomers selected from the group consisting of halogenated alkenyl ethers, halogenated alkenyl esters, and halogenated (meth)acrylates are useful in various end-use applications wherein the presence of halogen (e.g., fluorine) in the copolymer imparts one or more desirable properties, as compared to analogous copolymers not containing halogen.

  • Publication number: 20200283351
    Abstract: A method for synthesizing halogenated organic compounds, such as halogenated alkenyl group-containing and halogenated alkyl group-containing compounds having a heteroatom (e.g., O,N.S) coupled to a carbon atom of a halogenated alkenyl or halogenated alkyl group, involves reacting a halogenated olefin such as a chloro-substituted trifluoropropenyl compound with an active hydrogen-containing organic compound such as an alcohol (e.g., an aliphatic monoalcohol, aliphatic polyalcohol, or a phenolic compound), a primary amine, a secondary amine or a thiol.

  • Patent number: 5621112
    Abstract: A process is disclosed for the preparation of the herbicide ethyl .alpha.-2-dichloro-5-[4-(difluoromethyl)-4,5-dihydro-3-methyl-5-oxo-1H-1,2 ,4-triazol-1-yl]-4-fluorobenzenepropionate by the simultaneous diazotization of 4-difluoromethyl-4,5-dihydro-3-methyl-5-oxo-1-(5-amino-2-fluoro-4-chloro-p henyl)-1H-1,2,4-triazole (the Amine) and arylation of ethyl acrylate with the diazotized Amine. In the process the following reagents are added in sequence and, under specified conditions, to a cooled, stirred solution of the Amine in acetone: cuprous chloride, hydrochloric acid, ethyl acrylate, and sodium nitrite.

  • Patent number: 5468868
    Abstract: This invention provides a process for optimizing the yield of a 1-(2,4-dichlorophenyl)-4,5-dihydro-1H-1,2,4-triazol-5-one by the chlorination in two steps of a 4,5-dihydro-1-phenyl-1H-1,2,4-triazol-5-one. The critical first step is the selective chlorination of the phenyl ring in the 4-position by addition of chlorine to a solution of the 4,5-dihydro-1-phenyl-1H-1,2,4-triazol-5-one in N,N-dimethylformamide. Chlorination of the product of the first step in acetic acid/water yields the 1-(2,4-dichlorophenyl)-4,5-dihydro-1H-1,2,4-triazol-5-one in high yield.
