  • Patent number: 8871916
    Abstract: A method for making diazo-compounds, diazonium salts thereof and other protected forms of these compounds. Diazo-compounds are prepared by reaction of a tertiary phosphine reagent carrying a reactive carbonyl group with an azide. The reaction can also generate an acyl triazene which can be converted thermally or by addition of base to form the diazo-compound or the acyl triazene can be isolated. The method is particularly useful for conversion of azides carrying one or more electron withdrawing groups to diazo-compounds. The method can be carried out in aqueous medium under mild conditions and is particularly useful for conversion of azido sugars to diazo-compounds and diazonium salts thereof under physiological conditions. Tertiary phosphine reagents, particularly those that are water-soluble, and precursors for preparation of the reagents are provided.

  • Patent number: 7198712
    Abstract: For desulfurization and, if necessary, for denitrification of hydrocarbon fractions the hydrocarbon mixture is brought into contact with a non-aqueous ionic liquid of general formula Q+A?, wherein Q+ is a ammonium, phosphonium or sulfonium cation, that contains at least one alkylating agent of the formula RX?, making it possible to form ionic sulfur-containing derivatives (and, if necessary, nitrogen-containing derivatives) that have a preferred solubility in the ionic liquid; and the ionic liquid is separated from the hydrocarbon mixture that is low in sulfur and nitrogen by decanting.

  • Patent number: 6956127
    Abstract: Disclosed are methods of preparing monoalkyl Group VA metal dihalide compounds in high yield and high purity by the reaction of a Group VA metal trihalide with an organo lithium reagent or a compound of the formula RnM1X3?n, where R is an alkyl, M1 is a Group IIIA metal, X is a halogen and n is an integer fro 1 to 3. Such monoalkyl Group VA metal dihalide compounds are substantially free of oxygenated impurities, ethereal solvents and metallic impurities. Monoalkyl Group VA metal dihydride compounds can be easily produced in high yield and high purity by reducing such monoalkyl Group VA metal dihalide compounds.
