除了作为分子共轭化学中的共价接头外,由铜 (I) 催化的叠氮化物 - 炔环加成反应产生的 1,2,3-三唑基部分作为金属离子配体的功能受到了相当多的关注。在这项工作中,我们表征了在荧光锌 (II) 指示剂开发的背景下,在多齿配体支架中加入 1,2,3-三唑基对金属配位的热力学和动力学影响。配体L14、BrL14和FL14(1,4-异构体)包含 1,4-二取代的 1,2,3-三唑基,该基团能够与多齿内的二(2-甲基吡啶氨基)(DPA) 部分结合的锌 (II) 结合配体支架。因此,1,4-异构体中的1,2,3-三唑基在螯合中是“整合”的。1,5-异构体L15、BrL15和FL15含有 1,2,3-三唑基,它们被排除在锌 (II) 配位之外。这些 1,2,3-三唑基是“被动接头”。使用1 H NMR 光谱和等温滴定量热法 (ITC)鉴定溶液中化学计量比为 2:1(配体/金属)的锌 (II) 配合

1. La synthèse de triazoles substitués est réalisable par chauffage prolongé d'un azide organique et d'un composé acétylénique dissous dans un solvant approprié (généralement le toluéne). Les éthynylcarbinols, en particulier, donnent des hydroxyalcoyl-triazoles, le groupe OH étant porté dans la chaîne alcoylique par l'atome de carbone lié au cycle. A partir de composés acétyléniques asymétriques, deux
A general route to 1,5-disubstituted 1,2,3-triazoles with alkyl/alkyl, alkyl/aryl, aryl/aryl combinations: a metal-free, regioselective, one-pot three component approach

An experimentally simple one-pot reaction, affording 1,5-disubstituted 1H-1,2,3-triazoles in good to excellent yields by combining vinyl sulfones, sodium azide and alkyl bromides, -tosylates, -mesylates or aryl amines, -iodides is reported. The organic azides, generated in situ react with vinyl sulfones in a regioselective fashion in the absence of metal ions. Unlike many of the recently reported strategies, this method is capable of generating alkyl/alkyl, alkyl/aryl and aryl/aryl containing 1,5-disubstituted 1,2,3-triazoles under simple reaction conditions.

than the peripherally substituted zinc complex (4). In addition, quantum yields for singlet oxygen generation (ΦΔ = 0.32 for silicon complex (4) and ΦΔ = 0.76 for zinc complex (5) in DMSO) were obtained. Electrochemical studies show that complex5 is present in non-aggregated form as a result of steric hindrance of the axial groups; the LUMO level of this complex is slightly more negative than the conduction
