Abstract: A natural oriental medicinal composition for the promotion of hair growth is provided. The oriental medicinal composition includes a black bean extract, a tangerine extract, a potato extract, a pine needle extract and a quartzite powder. Since the oriental medicinal composition includes crude drugs extracted from natural substances that can prevent hair loss, it is effective for hair growth and has ensured biostability. Particularly, the oriental medicinal composition allows newborn hair to grow in the form of stiff hair.

Abstract: A method of manufacturing a cyano compound by reacting a carbonyl compound with a nitrile compound having at least one ?-hydrogen atom in the presence of a ligand and a metal compound of formula (III), MX??(III) wherein M is a copper atom or a silver atom, and X is an alkoxy group, an alkyl group, an aryl group or an anionic residue.

Abstract: A catalyst comprising at least one complex of a metal of transition group VIII comprising at least one monodentate, bidentate or multidentate phosphinamidite ligand in which the phosphorus atom and the oxygen atom of the phosphinamidite group form part of a 5- to 8-membered heterocycle can be used for the hydroformylation and hydrocyanation of compounds containing at least one ethylenically unsaturated double bond. The phosphinamidite ligand is, for example, represented by the following formulae wherein represents an optionally substituted 5- to 8-membered heterocycle wherein A represents carbon ring members; represents an optionally substituted N-bonded heterocycle wherein (Het) indicates optional ring heteroatoms in addition to the N; and B is a carbon-carbon single bond or a divalent bridging group.

Abstract: A catalyst which comprises at least one complex of a metal of subgroup VIII having at least one bidentate phosphonite ligand of the formula I or salts and mixtures thereof, a process for the preparation of mixtures of monoolefinic C5-mononitriles, a process for the catalytic isomerization of branched aliphatic monoalkenenitriles and a process for the preparation of adiponitrile.

Abstract: The invention relates to a catalyst which comprises at least one complex of a metal of group VIII, which comprises at least one uni-, bi- or multidentate phosphinite ligand in which the phosphorus atom and the oxygen atom of the phosphinite group are part of a 5- to 8-membered heterocycle, and to processes for hydroformylation and hydrocyanation of compounds which contain at least one ethylenic double bond in the presence of a catalyst of this type.

Abstract: 2-Butene-1,4-diol and/or 3-butene-1,2-diol are (is) reacted with hydrogen cyanide in the presence of a molten catalyst comprising a cuprous halide and a non-aromatic organic amine hydrohalide.

Abstract: The present invention relates to the production of a norcamphane dicarbonitrile and is directed to solving the problems of low conversion from the starting material, low selectivity and uneconomical production.According to the present invention, a norcamphane dicarbonitrile is produced by hydrocyanation of bicyclo [2,2,1]-5-heptene-2-carbonitrile in the presence of a zero-valent nickel complex catalyst and a Lewis acid.

Abstract: Hydrocyanation of penetenenitriles using cyanohydrins as the HCN source and in which a solid dissociation additive is present in a slurry to facilitate the dissociation of the cyanohydrin.

Abstract: The present invention relates to the synthesis of nitriles having an amine function on the adjacent carbon.

Abstract: Paramethyl-substituted hindered phenols are selectively oxidized by contacting with an oxidizing agent at elevated temperatures in the presence of a heterogeneous oxidative coupling catalyst. In the absence of an optional nucleophile the products comprise carbon-carbon oxidative coupling products. In the presence of a nucleophile, addition products result that may be further oxidized by continued exposure to the oxidizing agent to yield substituted p-hydroxybenzaldehydes.

Abstract: Process of polyene hydrocyanation, in particular diene hydrocyanation, wherein a promotionally effective amount of any acid with a pK.sub.a above about 2 and below and 14, preferably aryl alcohols such as phenol and cresols, is used.
