with copper(II) chloride and copper(II) bromide have been studied in different chemical environments. Copper(II) chloride assisted C S bondcleavage of the organic moieties leading to the formation of copper(II) picolinate derivatives, whereas, under similar experimental conditions, no C S bondcleavage was observed in the reaction with copper(II) bromide. The resulted copper(II) complexes isolated
摘要 具有 N2S2 供体组 [L 1 = 1,2-双(2-吡啶甲硫基)乙烷,L 2 = 1,3-双(2-吡啶甲硫基)丙烷和 L 3 = 1,4-双(2-吡啶基甲硫基)丁烷]与氯化铜 (II) 和溴化铜 (II) 在不同的化学环境中进行了研究。氯化铜 (II) 辅助有机部分的 CS 键断裂,导致形成吡啶甲酸铜 (II) 衍生物,而在类似的实验条件下,在与溴化铜 (II) 的反应中未观察到 CS 键断裂。从不同介质中分离得到的铜 (II) 配合物已通过光谱和 X 射线晶体学工具进行了表征。
Copper(II) complex of in situ formed 5-(2-pyridyl)-1,3,4-triazole through C–S bond cleavage in 1,2-bis(2-pyridylmethylthio)-bis-ethylsulphide: Synthesis, structural characterization and DNA binding study
2-bis(2-pyridylmethylthio)-bis-ethylsulphide (L) with copper(II) chloride in presence of an excess of azide ions led to the formation of a new copper(II) complex formulated as [Cu(2-PTrz) 2 (H 2 O) 2 ] ( 1 ), where 2-PTrz = 5-(2-pyridyl)-1,3,4-triazole is formed through the cleavage of C–S bond in L promoted by copper(II) chloride. The precursor of 1 is the in situ formed Cu(pic) 2 derivative (pic = 2-picolinate)
