  • Patent number: 4829091
    Abstract: An improved method for the decarbalkoxylation of alkylated .beta.-keto esters to obtain high yields of ketones. In accordane with the method, decarbalkoxylation of alkylated .beta.-keto esters is accomplished by heating the esters in the presence of dilute aqueous alkali and an effective amount of a phase-transfer agent. The method produces commercially practical yields of ketone in a manner which is facile, economical and environmentally safe. Novel methylene-linked pyrethroid ketones produced from the improved method exhibit insecticidal activity against various agricultural pests.

  • Patent number: 4814508
    Abstract: Aromatic carbonyl compounds, in particular arylene ether ketones, are prepared by reacting an appropriate reagent system in the presence of free Lewis acid and a complex between a Lewis acid, for example, aluminum trichloride, and a Lewis base, for example, N,N-dimethylformamide, and, optionally, a diluent, such as methylene chloride. The process is particularly advantageous for the preparation of substantially or all para-linked arylene ether ketones as the presence of the Lewis acid/Lewis base complex markedly reduces alkylation and ensures the substantial absence of ortho substitution.

    Abstract: The invention relates to a novel fluorinated pre-polymer and novel process steps in producing the same. The pre-polymers are quinoxaline materials derived by reaction of diketone linkage containing perfluoro-compounds with an aromatic diamine. The diketone is produced by oxidatively dechlorinating a polychloroketone which may be a monoketone or a bis-ketone. The polychloroketone is produced by reacting a keto-ylid with a chlorinating agent, e.g., chlorine. The keto-ylid is produced by reacting a phosphorane with an acid halide of a polyoxy-perfluoroalkylene oxide wherein the perfluoro-oxyalkylene group contains two or three carbon atoms, and there are present from two to twenty perfluoro-oxyalkylene units in the oligomer. The quinoxalines, the polychloroketones and the diketones hereof are novel products. Cross-linking may be effected with a free radical generator.
