    摘要:分离出几种通式 (Pph(3))(2)(Co)Rhr (R = P-Tolyl,O-Tolyl,Me) 的有机铑 (I) 配合物,并显示将芳基醛插入芳基-铑(一)债券.在非水条件下,这些反应以非常好的收率提供酮.芳基铑 (I) 配合物的稳定性使这些反应也可以在 Thf 和水的混合物中进行.在该溶剂系统中,仅生成二芳基甲醇.机理研究支持通过将醛插入铑-芳基键并随后β-氢化物消除或水解形成二芳基酮或二芳基甲醇产物来形成酮和二芳基甲醇.Thf/水混合物中的动力学同位素效应和二芳基甲醇的形成与酰基碳氢键的氧化加成和还原消除形成酮不一致.此外,在反应过程中直接观测到由醛插入形成的中间体二芳基甲醇铑.其结构由独立合成证实.该复合物经过β-氢消除以形成酮.该醇盐还与第二个醛反应,通过插入和随后的β-氢消除形成酯.因此,芳铑配合物与过量醛的反应通过双插入和β-氢消除序列形成酯.其结构由独立合成证实.该复

    标 题:Dispersant for use in synthesis of polyaryletherketones

    摘要:A method for forming a polyaryletherketone is described. More particularly, a reaction mixture is initially supplied to the reactor vessel that contains one or more precursor monomers. A heteroaryl compound is also added to the reaction mixture. The reaction can be carried out according to, e.g., an electrophilic aromatic substitution reaction or a nucleophilic aromatic substitution reaction. The heteroaryl compound can serve as a dispersant to the polymer as it is formed. This minimizes the likelihood of gelling of the product polymer within the reactor vessel and limits the impact of process disruptions on the production of the polyaryletherketone.

    摘要:Antimalarial agents having a novel pharmacophore of formula (I) are herein described. These polycyclic compounds are able to inhibit chloroquine-sensitive and chloroquine-resistant strains of Plasmodium falciparum (Pf). Furthermore, the synthesis of these compounds involves few steps from commercial products with low cost of production.
