摘要:高碘酸钾(kio 4)/ Nano 2 / Khso 4)引发的芳香族化合物硝化反应的合成和动力学已经在乙腈水溶液中进行了研究.硝基芳族化合物的合成是在常规且无溶剂的微波条件下完成的.微波辅助反应的反应时间比常规反应要短.在硫酸氢盐和乙腈水溶液中硝化苯酚的反应动力学表明,其对[苯酚],[nano 2 ]和[kio 4 ]具有一级依赖性.[khso 4的增加在其他类似条件下,可加快硝化速度.在高介电介质的溶剂(具有高介电常数(d)的溶剂)中,硝化速率增加.观测到的结果与amis和kirkwood图一致[log K '与(1 / D)和[(d − 1)/(2 D +1)].这些观察结果可能表明阴离子种类和分子或(偶极)种类参与了速率测定步骤.此外,(log K')与有机溶剂的体积%呈线性关系,这可能表明静电和非静电力,苯酚硝化过程中溶剂-溶质相互作用的重要性.反应速度随着给电子基团的引入而加速

摘要:Substituted amino aromatic compounds such as 3-amino-4-hydroxybenzoic acid are prepared by electrolytically reducing the corresponding nitro aromatic compound in a basic medium at temperatures below 60° C. and current densities greater than 50 milliamps per square centimeter. The aminohydroxybenzoic acids are useful in the preparation of polybenzoxazoles which are used to make fibers and composites having high strength and thermal stability.

摘要:Radiolabeled tracers for sulfotransferases (SULTs), their synthesis, and their use are provided. Included are substituted phenols, naphthols, coumarins, and flavones radiolabeled with 18 F, 123 I, 124 I, 125 I, or 11 C. Also provided are in vivo techniques for using these and other tracers as analytical and diagnostic tools to study sulfotransferase distribution and activity, in health and disease, and to evaluate therapeutic interventions.
