标 题 :Process for the preparation of phenyl ketones
发明人：DESBOIS MICHEL
权利人:RHONE POULENC SPEC CHIM
摘要:A process for the preparation of phenyl ketones, characterized in that, in a first stage, a halo- or trihalomethylbenzene is reacted with a trihalomethylated aliphatic or aromatic compound in the presence of boron trifluoride in an amount such that the absolute pressure of boron trifluoride within the reaction vessel exceeds 1 bar, and in the presence of hydrofluoric acid as a solvent, and in that, in a second stage, the resultant product is hydrolyzed. The products are used as intermediates in the synthesis of compounds having a pharmaceutical or phytosanitary (e.g., herbicidal) activity.

摘要:A process for the acylation of halo- or trihalomethylbenzenes, wherein a halo- or trihalomethylbenzene is reacted with a carboxylic acid, a precursor or a derivative thereof in the presence of boron trifluoride in an amount such that the absolute pressure of the boron trifluoride within the reaction vessel exceeds 1 bar, and in the presence of hydrofluoric acid as a solvent. The resultant products are useful as intermediates in the synthesis of compounds having a phytosanitary (e.g., herbicidal) or pharmaceutical activity.

摘要:A process for producing a benzhydrol compound (II) which comprises hydrogenating a benzophenone compound (I) in the presence of a hydrogenation catalyst consisting of a transition metal complex, a base and an optically active diamine compound: (I) (II) wherein R1 to R10 each represents H, OH, C1-4 alkyl, C1-4 alkoxy, C1-4 alkanoyl, etc., R2 and R3, and R8 and R9 may form -CH=CH-CH=CH-, or any two of R1 to R9 adjacent to each other may be bonded to thereby form -OCH2O- or -(CH2)3-. By using this process, optically active benzhydrol compounds which have a high purity and are useful as, for example, intermediates in the synthesis of drugs can be produced by simple procedures.
