标题:Process for the synthesis of isocyanates and of isocyanate derivatives

权利人:POUDRES & EXPLOSIFS STE NALE
摘要:The present invention relates to a process for the synthesis of isocyanates and of isocyanate derivatives. Isocyanates are obtained by reacting an organic halide with a metal cyanate in an organic medium in the presence of a catalyst consisting of a complex of nickel with at least one organic ligand, in which complex the nickel is in the zero oxidation state. A carbamate or a urea, respectively, are obtained by a subsequent reaction with a hydroxy compound or a primary or secondary amine. Isocyanates and their derivatives are used especially either as refined synthesis agents for the production of pesticides and medications, or as monomers or comonomers for the preparation of many macromolecular compounds.

摘要:The invention relates to processes for the synthesis of tertiary phosphine oxides and sulfides. The process according to the invention consists, in a first step, of reacting a secondary phosphine oxide or sulfide with an optionally activated alkali metal amide, and, in a second step, of reacting the mixture obtained in the first step with an organic halide containing at least one halogenophenyl radical or one halogenomethyl group. Tertiary phosphine oxides and sulfides are complexing agents of high stability.

标题:Method for preparing halogenated compound from metal halide salt on basis of mobile phase

摘要:Disclosed is a method for preparing a halogenated compound from a metal halide salt on the basis of a mobile phase. The method comprises: converting an aromatic hydrocarbon, alkane or nitrile compound into a halogenated compound by means of a cheap metal halide salt and a photocatalyst under illumination. The method uses a cheap and safe halide salt as a halogen source, does not introduce additional elemental halogen or an additional oxidant, can implement a reaction at normal temperature and normal pressure, is high in terms of selectivity and friendly to environment, and can be used for replacing an existing synthesis reaction system for halogenated compounds. A mobile phase device is used to replace a tank reactor, such that operation is easy and convenient, the price is low, the substrate adaptability is high, the continuous synthesis of halogenated compounds can be achieved, and the method is suitable for industrial large-scale production.

标 题:Synthesis of aldehydes and products of such synthesis
发明人：MEYERS ALBERT I
权利人:UNIV LOUISIANA STATE
摘要:The disclosure describes the production of complex aliphatic, unsaturated and cycloalkane aldehydes utilizing heterocyclic ring compounds, such as oxazines, particularly dihydro-1,3-oxazines. The oxazines are treated with an alkali metal-alkane compound, such as butyl lithium in the presence of an organic solvent at subzero temperature to form an anion of the oxazine. This anion is then alkylated in the anhydrous reaction mixture by introduction of a suitable halide, epoxide or ketone while still at a subzero temperature and mixture is permitted to warm up to room temperature, following which the reaction mixture is acidified, as with hydrochloric acid to pH 2 to 3, extracted and then made basic, as with caustic alkali with cooling. n The reaction mixture is then extracted, as with ether, to produce after evaporation the alkylated dihydro-1,3-oxazine. n The alkylated dihydro-1,3-oxazine is then reacted with an alkali metal or sodium borohydride or borodeuteride or borotritide, with cooling to subzero temperatures at about a neutral pH and then transferred into a basic aqueous environment following extraction of the aqueous layer with an organic solvent, such as ether, to give a tetrahydro-1,3-oxazine. This compound may then be converted to the aldehyde desired by steam distillation or by hydrolysis in the presence of a dilute or weak acid, such as hydrochloric or oxalic acid. The aldehydes may then be extracted. n These aldehydes are useful as components or intermediates in flavoring or perfumes, in insect attractants and repellants, and in pharmaceuticals.

权利人:PHILLIPS PETROLEUM CO
摘要:An organic ester is produced by conversion of an organic halide employing excess alkali metal carboxylate. A resultant reaction mass including solids comprised of alkali metal halide is obtained containing occluded in the solids portion an amount of otherwise difficult-to-recover desired ester product. At least a portion of said solids is recycled to the conversion whereby to prevent further occlusion of desired product. In an embodiment of the invention, potassium acetate salt is recycled for reuse.

摘要:A novel process for the synthesis of fenofibrate, includes reacting a metal salt of fenofibric acid with an isopropyl halide, in a solvent system composed of a mixture of dimethyl sulfoxide and a C 2 -C 4 alkyl acetate. The process can be used on an industrial scale and makes it possible to obtain a fenofibrate of a quality in accordance with the Pharmacopoeia without the need for purification by recrystallization.
