摘要:氯代芳烃的电化学还原与供电取代基(如氯甲苯,-苯甲醚和-酚)进行研究.在铅或碳阴极下,在各种溶剂支持电解质的电位静态和电流静态条件下进行制备电解.在适当条件下,可能对具有两个或更多氯取代基的化合物进行部分和主要区域选择性的去氯化.尤其是在对位,替换一个单独的氯取代基是困难的.因此,高度有毒和持久的寡氯衍生物可以转化为氯化程度较低的问题较少的化合物.通过电还原,也可以显着降低受氯化酚和nitrofen®污染的土壤提取物等实际材料的氯含量.

标题 :Preparation of p-fuchsones and synthesis of p-dihydroxylated aromatic compounds therefrom
发明人：COSTANTINI MICHEL; MANAUT DANIEL; MICHELET DANIEL
权利人:RHONE POULENC CHIMIE
摘要:p-Dihydroxylated aromatic compounds are prepared via the oxidation of p-fuchsones, the latter advantageously being synthesized by reacting a phenolic compound having at least one hydrogen atom in the para-position to the hydroxyl function with a non-enolizable ketonic compound, in the presence of a catalytically effective amount of an acid catalyst and, optionally, a cocatalytically effective amount of an ionizable sulfur-containing compound.

发明人：MCALPINE SHELLI R; TAYLOR RACHEL E; BOLLA MEGAN L; SEGALL ANCA M
摘要:The invention provides a method for making a combinatorial library of cyclic compounds, such as Holliday junction-trapping compounds, comprising the steps of (a) obtaining a plurality of trimers according to the generic structure X 1- X 2- X 3 , wherein X 1 , X 2 and X 3 can be independently any naturally or nonnaturally occurring amino acids or peptidomimetics thereof; (b) optionally coupling a spacer S to the trimer at either end; (c) cyclizing two trimers or trimer-spacer conjugates in a head-to-tail orientation; thereby obtaining a combinatorial library of compounds, wherein the library does not include an unmodifed or naturally occurring Holliday Junction-trapping compounds. The invention additionally provides methods macrocyclic compounds that are synergimycin derivatives.

标 题:Process for the preparation of metachlorophenols
发明人：CORDIER GEORGES
权利人:RHONE POULENC SPEC CHIM
摘要:The invention relates to a process for the preparation of metachlorophenols. The process consists in selectively hydrodechlorinating, under the action of heat and in the liquid phase, polychlorophenols containing at least one chlorine atom in the meta position relative to the phenolic hydroxyl, by reacting these polychlorophenols with hydriodic acid in a quantity which is sufficient in relation to the chlorine atoms to be removed. The metachlorophenols obtained are organic synthesis intermediates.
