标题:取代的甲基:取代作用
摘要:由f 19 NMR确定了一系列单取代,二取代和三取代的me基团ch 2 X,Chx 2和cx 3的取代基参数,其中x为f,Cl,Br,Ome,Scf 3和cn对相应的间-和对-氟甲苯进行测定.仅对于氰基取代基发现了取代的加成线性效应.消散后,对于x为f,Cl,Br和scf 3(尤其是氯和溴)的基团,观测到的饱和效应归因于这些取代基的未共享p电子与环的π系统的空间相互作用.

标题 :Process for the manufacture of fluorinated benzenes and fluorinated benzophenones, and derivatives thereof
发明人：ZHOU CHANGYUE; DU HONGJUN; WU WENTING
权利人:FUJIAN YONGJING TECH CO LTD
摘要:The invention relates to a new process for the manufacture or synthesis, respectively, of fluorinated benzenes and fluorinated benzophenones, and derivatives thereof, in particular of fluorobenzenes and derivatives thereof. The present invention particularly pertains to a novel environmentally friendly process for the synthesis of fluorinated benzenes and benzophenones as raw materials for the manufacture of polyaryletherketones (PAEKs).

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 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.

标题:Process for the simultaneous halogenation and fluorination of aromatic derivatives
发明人：DESBOIS MICHEL; DISDIER CAMILLE
权利人:RHONE POULENC SPEC CHIM
摘要:A process for the stimulaneous halogenation and fluorination of aromatic derivatives substituted by at least one group containing a halogenoalkyl unit. The aromatic derivative is reacted with the halogen in liquid hydrofluoric acid. The products obtained are useful as intermediates for the synthesis of compounds having a plant-protecting or pharmaceutical activity.
