标题:Synthesis Of Structurally Diverse Diarylketones Through The Diarylmethyl Sp3 Ch Oxidation
摘要:Under Open-Flask Conditions,An Efficient Method To Assemble A Series Of Diversely Functionalized Diarylketones In The Presence Of Commercially Available Nbs Has Been Developed. Yields Of Up To 99% Have Been Achieved Employing Diarylmethanes As Starting Material. Based On O-18-Labeled Experiment,The Addition Of Stoichiometric Water Eventually Leads To Excellent Yields In All Carbonylation Cases. (C) 2014 Elsevier Ltd. All Rights Reserved.

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.

发明人：DESBOIS MICHEL
权利人:RHONE POULENC SPEC CHIM
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.

权利人:UNIV KING FAHD PET & MINERALS
摘要:A method for enhancing the conductivity of MOF-5 by the development of an MOF-5 polymer composite material. The composite material incorporates a conductive polymer, preferably polyaniline, in the solvo-thermal synthesis pathway of MOF-5. The electrically conductive MOF-5 composite exhibits electric conductivity three orders of magnitude higher than that of MOF-5 while maintaining the crystallinity, robustness, and thermal stability of MOF-5.

标题 :Aromatic ketone synthesis with amide reagents and related reactions
发明人：KLUMPP DOUGLAS A; RAJA ERUM K
权利人:KLUMPP DOUGLAS A; RAJA ERUM K; UNIV NORTHERN ILLINOIS
摘要:A method of preparing an aryl carbonyl or aryl thiocarbonyl compound, comprises reacting an N-(nitroaryl)-amide or N-(nitroaryl)-thioamide with an aromatic ring, with a superacid catalyst, to produce the aryl carbonyl or aryl thiocarbonyl compound. The superacid is present in an amount of at most 8 equivalents in proportion to the N-(nitroaryl)-amide or N-(nitroaryl)-thioamide. A method of preparing aryl amide or aryl thioamide, comprises reacting an N-(nitroaryl)-carbamide or N-(nitroaryl)-thiocarbamide with an aromatic ring, with a superacid catalyst, to produce the aryl amide or aryl thioamide.
