Utilization of a new gold/Schiff-base iron(<scp>iii</scp>) complex composite as a highly sensitive voltammetric sensor for determination of epinephrine in the presence of ascorbic acid
The preparation of new materials that can act as systems capable of sensing biologically relevant molecules constitutes a significant modern challenge as well as a necessity oriented towards disease prevention. Subcomponent self-assembly of 2-(methylhydrazino)benzimidazole, 4-tert-butyl-2,6-diformylphenol and Fe(ClO4)2(H2O)6 leads to a new, bimetallic iron(III) complex of the following formula: [F
Subcomponent self-assembly gives a new family of the triple-stranded helicates of the LnIII2O3}3− core (Ln = Tb, Dy, Ho, Er, Tm and Yb) yielding an erbium congener revealing field-induced SMM characteristics.
hydrosilylation of alkynes, which was established only recently. Previous articles about transition metal-catalysed double hydrosilylation show that terminal aryl alkynes are a challenge. We report on cobalt(II) and iron(III) complexes with the easy-to-synthesise N,N,N-tridentate hydrazone ligand being active precatalysts in Markovnikov-selective double hydrosilylation of terminal aryl alkynes. The influence
孪晶双(硅烷)是具有有趣特性的独特化合物。获得它们最直接的方法是炔烃的双氢化硅烷化,这是最近才建立的。之前关于过渡金属催化的双氢化硅烷化的文章表明,末端芳基炔烃是一个挑战。我们报道了钴 ( II ) 和铁 ( III ) 配合物以及易于合成的N , N , N-三齿腙配体是末端芳基炔烃的马尔可夫尼科夫选择性双氢化硅烷化反应中的活性预催化剂。研究了腙配体结构的影响和三乙基硼氢化钠活化剂的潜在作用。合成了具有两个相同或不同甲硅烷基的孪生双(硅烷)组,显示了所报告方法的适用性。
