    摘要: Arylalkylamines (as the hydrochloride salt), e.g. tyramine hydrochloride, are prepared by hydrogenating substituted or unsubstituted aryl-.alpha.-oximinoalkyl ketones, e.g. p-hydroxyisonitroacetophenone, in either in an aqueous reaction medium comprising hydrochloric acid, essentially without the presence of a lower alkyl alcohol in said reaction medium, or in an aqueous reaction medium comprising water, hydrochloric acid, and a lower alkyl alcohol, wherein the alcohol comprises less than about 90% by volume of the reaction medium. A substituent on the aryl portion of the aryl-.alpha.-oximinoalkyl ketone must be on a position which activates the aromatic ring.

    摘要: A process of acylating a monocyclic phenolic reactant, e.g. phenol to a hydroxy aromatic ketone, e.g. 4-hydroxyacetophenone, by contacting the phenolic reactant with about 0.4 to 0.8 moles of a carboxylic acid anhydride, e.g. acetic anhydride as acylating agent per mole of phenolic reactant of in the presence of a Friedel-Crafts catalyst, e.g. hydrogen fluoride. The process generally results in phenolic reactant conversions of at least about 80% and reaction selectivities to hydroxy aromatic ketone of at least about 70%.

    摘要: A method is provided for the preparation of ibuprofen by carbonylating 1-(4'-isobutylphenyl)ethanol (IBPE) with carbon monoxide comprising initially a reaction mixture comprising IBPE, ibuprofen and a catalyst for the carbonylation with carbon monoxide under conditions to initiate the reaction, and continuing to feed carbon monoxide to the composition to produce the desired yield of ibuprofen. Preferably the catalyst comprises palladium and a monodentate phosphine ligand. The presence of ibuprofen in the feed composition when the reaction is initiated with CO makes it possible to obtain high selectivities to ibuprofen with substantially complete conversion of IBPE at much shorter reaction times than if no ibuprofen is present initially.

    摘要: Substituted phenethanol ethers are prepared by the catalytic reduction of corresponding substituted phenylglyoxal acetals. The catalytic reduction is carried out by reacting a substituted phenylglyoxal acetal with hydrogen in the presence of an acid catalyst and a metal catalyst. Certain substituted phenylglyoxal acetals, and more particularly, 4-hydroxyphenylglyoxal dialkyl acetals are prepared by reacting 4-hydroxyacetophenone with a primary or a secondary alkyl alcohol in the presence of a hydrogen ion (H+) source and a nitrosonium ion (NO+) source.
