    摘要: A process for producing BrSF5 includes providing a first reactant including a metal fluoride of fluorine and a metal M selected from the group consisting of alkali metals, alkaline earth metals, and Ag, providing a second reactant including BrF3, combining the first reactant and the second reactant to form a mixture, wherein the first reactant and the second reactant are allowed to contact for a period of time sufficient to produce MBrF4 in an amount stoichiometrically equivalent to a quantity of BrF3, and providing a third reactant including SF4, wherein the third reactant reacts with MBrF4. The process for producing BrSF5 can further include providing a fourth reactant including Br2, wherein the fourth reactant is provided before, during and/or after providing the first reactant, the second reactant and/or the third reactant. BrSF5 is produced in a yield of from about 50% to about 99.99% based on the amount of SF4.

    摘要: A process for fluorinating &bgr;-dicarbonyls to form the corresponding &agr;-fluorinated-&bgr;-dicarbonyl compounds is provided. The process is represented by the following reaction scheme: where R1 is H, alkyl or alkoxy, R2 is H, alkyl or perfluoroalkyl, and R3 is H, Cl, Br, I or alkyl. Use of oxygen in the fluorine stream yields a product which is 90-96% pure and contains radical fluorination impurity levels which are 10-20% lower than when oxygen is not used.
