Abstract The characterization of the products of reactions between anhydrous/hydrated copper(II) acetate and the title acids having R = Me, C6H11, Ph and p-tolyl in different solvents and at different temperatures with the help of elemental analysis, TGA, DTA, room temperature magnetic susceptibility, IR, and UV-VIS and EPR spectral data reveal that a competition exists between the chelation of arsine
摘要借助元素分析,TGA,DTA表征了在不同溶剂和不同温度下无水/水合乙酸铜(II)与标题酸R = Me,C6H11,Ph和对甲苯基之间的反应产物,室温磁化率,IR,UV-VIS和EPR光谱数据表明,在一侧side与铜(II)的螯合与铜(II)还原为铜(I)及其后续反应之间存在竞争rs与铜(I)的螯合和/或oxide氧化铁与铜(II)的螯合。 预期通常由基团R的诱导作用控制的竞争被反应条件的改变所干扰,从而得出结论:反应条件而不是基团R的诱导作用控制了反应方式。
