    摘要: A process for the manufacture of an acetylenically unsaturated alcohol comprising reacting formaldehyde, an aldehyde or a ketone (a carbonyl compound) with acetylene in the presence of ammonia and an alkali metal hydroxide, the molar ratio of the alkali metal hydroxide to the carbonyl compound being less than 1:200. The reaction products, which depending on the starting carbonyl compound are propargyl alcohol or 1-monosubstituted or 1,1-disubstituted derivatives thereof, are of use as intermediates in the synthesis of many useful end products, inter alia in the field of vitamins and carotenoids.

    摘要: A process for producing organic sulfur acid or a salt thereof of the present invention allows an organic substrate to react with a sulfur oxide in the presence of a metallic compound catalyst and in the absence of N-hydroxy and N-oxo cyclic imide compounds and thereby yields a corresponding organic sulfur acid or a salt thereof. Such organic substrates include, for example, (a) homocyclic or heterocyclic compounds having a methylene group, (b) compounds having a methine carbon atom, (c) compounds having a methyl group or methylene group at the adjacent position to an unsaturated bond, (d) non-aromatic heterocyclic compounds having a carbon-hydrogen bond at the adjacent position to a hetero atom, and (e) straight-chain alkanes. The sulfur oxide includes, for example, sulfur dioxide. This production process can efficiently produce an organic sulfur acid or a salt thereof under mild conditions.

    摘要: Nitrophenyl hydroxy substituted acetylene, which can be converted to nitrophenylacetylene is prepared by reacting a nitrobromobenzene with a substituted terminal acetylene compound containing at least three carbon atoms and a hydroxy group on the carbon atom adjacent to the acetylene group in the presence of a dialkyl or trialkyl amine solvent and a catalyst system consisting of a palladium complex containing two halogen moities and two tri-substituted phosphine moieties. A cuprous iodide promoter is also employed in the reaction sequence.
