标 题 :Process for the preparation of α,α-difluoroalkyl-thiophenyl ketones
发明人：DESBOIS MICHEL
权利人:RHONE POULENC SPEC CHIM
摘要:A process for the preparation of alpha , alpha -difluoroalkoxy or alpha , alpha -difluoroalkylthiophenyl ketones, in which a polyhaloalkoxybenzene or a polyhaloalkylthiobenzene is reacted with a carboxylic acid, a precursor or a derivative of this acid in the presence of boron trifluoride in such an amount 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 phytosanitary (e.g., herbicidal) or pharmaceutical activity.

摘要:A process for the preparation of alpha , alpha -difluoroalkoxy or alpha , alpha -difluoroalkylthiophenyl sulfones, in which a polyhaloalkoxybenzene or a polyhaloalkylthiobenzene is reacted with a sulfonic acid, a derivative or a precursor of this acid, 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.

标题:Process for preparation of di- or trifluoromethoxyphenyl ketones or di- or trifluoromethylthiophenyl ketones
发明人：DESBOIS MICHEL
权利人:RHONE POULENC SPEC CHIM
摘要:A process for the preparation of di- or trifluoromethoxyphenyl ketones or di- or trifluoromethylthiophenyl ketones, characterized in that, in a first stage, a di- or trihalomethoxybenzene or a di- or trihalomethylthiobenzene is reacted with a trihalomethylated aromatic or aliphatic 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 product of the first stage is hydrolyzed. The resultant products are useful as intermediates in the synthesis of compounds having a pharmaceutical or phytosanitary (e.g., herbicidal) activity.
