标题:Process for the electrochemical synthesis of alpha-saturated ketones
发明人：GARNIER LAURENCE; ROLLIN YOLANDE; PERICHON JACQUES
权利人:POUDRES & EXPLOSIFS STE NALE
摘要:The present invention relates to a process for the electrochemical synthesis of alpha-saturated ketones by electrochemical reduction, in an organic solvent medium, of alpha-saturated organic halides in the presence of CO2 and of a catalyst based on nickel complexed with a bidentate organic ligand containing two nitrogen atoms, such as 2,2'-bipyridine and, optionally, with an ethylenic coligand. The anode, made of a metal chosen from the group consisting of the reducing metals and their alloys, is consumed during the electrochemical reaction whose site it is. It is preferably made of magnesium. This process is simple to use and allows a single-compartment cell to be employed. Alpha-saturated ketones are compounds commonly employed in the chemical industry, particularly as solvents or synthesis intermediates.

摘要:The invention relates to a process for the electrosynthesis of carboxylic acids of general formula R-COOH in which R is an organic radical by the electrochemical reduction, in the presence of carbon dioxide, of organic compounds corresponding to the general formula R-Y in which R is the above-mentioned organic radical and Y is a hetero atom-containing radical, the hetero atom of the radical Y, chosen from the group consisting of oxygen, nitrogen, sulphur andphosphorus, being directly linked to a carbon atom of the radical R by a single covalent linkage. When the hetero atom is nitrogen or phosphorus, the radical Y is an ammonium or phosphonium radical respectively. The anode, which is consumed during the electrosynthesis, is made of a metal chosen from the group consisting of reducing metals and their alloys, preferably made of magnesium, aluminium or zinc. This process without catalyst is very simple to perform and enables a cell with a single compartment to be employed. The carboxylic acids are commonly employed in the chemical industry, especially as intermediates for the synthesis of pharmaceutical products or of products used in plant protection.

标 题 :Synthesis of substituted triphenylenes, useful as discotic liquid crystals

摘要:Unsymmetrically substituted triphenylenes required in the synthesis of polymeric discotic liquid crystals are made using iron (III) chloride in organic solvent at room temperature to effect the oxidative coupling of 1,2-dialkoxybenzenes to 3,3',4,4'-tetraalkoxybiphenyls. This is followed by a reductive workup. The same oxidation-reduction protocol also proves effective in the trimerisation of 1,2-dialkoxybenzenes.

摘要:1,1,1-Trihalo-4-methylpentenes, carrying 2-substituents selected from those conjugate bases of Bronsted acids which are leaving groups in beta eliminations, are reduced electrochemically to 1,1-dihalo-4-methylpentadienes, intermediates in the synthesis of pyrethroid insecticides.

标题:Electrochemical deblocking solution for electrochemical oligomer synthesis on an electrode array
发明人：MAURER KARL; COOPER JOHN J
权利人:CUSTOMARRAY INC
摘要:There is disclosed an electrochemical deblocking solution for use on an electrode microarray. There is further disclosed a method for electrochemical synthesis on an electrode array using the electrochemical deblocking solution. The solution and method are for removing acid-labile protecting groups for synthesis of oligonucleotides, peptides, small molecules, or polymers on a microarray of electrodes while substantially improving isolation of deblocking to active electrodes. The method comprises applying a voltage or a current to at least one electrode of an array of electrodes. The array of electrodes is covered by the electrochemical deblocking solution.
