专利号:US-4157344-A 优先权日:1978-01-16 标题 :Preparation of aryl trifluoromethyl ethers 发明人:FEIRING ANDREW E 权利人:DU PONT 摘要:A one-step process for the synthesis of aryl trifluoromethyl ethers by reacting phenol or certain substituted phenols with a perhalomethane and hydrogen fluoride is provided. The compounds produced by the process of this invention are useful intermediates in the production of dyestuffs and pharmaceuticals.
专利号:US-4446078-A 优先权日:1982-01-21 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.

The resultant products are useful as intermediates in the synthesis of compounds having a phytosanitary (e.g., herbicidal) or pharmaceutical activity.
专利号:US-4438043-A 优先权日:1982-04-22 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.
专利号:US-4621160-A 优先权日:1983-06-23 标题 :Process for the chlorination of aromatic derivatives 发明人:DESBOIS MICHEL; DISDIER CAMILLE 权利人:RHONE POULENC SPEC CHIM 摘要:A process for the chlorination of aromatic derivatives. The aromatic derivative is reacted with chlorine gas in liquid hydrofluoric acid. The products obtained are useful as intermediates for the synthesis of compounds having a plant-protecting or pharmaceutical activity.
