H(2)L(2) and p-Cl for H(2)L(3)], were prepared by the condensation of salicylaldehyde with 2-(o-hydroxy aryl)azo} aniline. Reaction of H(2)L with VOSO(4) afforded the oxovanadium complex, (L)V(O)(H(2)O). The (L(1))V(O)(H(2)O) complex displays two reversible responses at 0.7 V and -0.65 V vs. SCE in cyclic voltammetry. Catalytic activity of (L(1))V(O)(H(2)O) toward H(2)O(2) induced oxidation of organic thioethers
游离配体2-(邻羟基芳基)偶氮} -1-N-水杨基苯胺H(2)L [其中H(2)L = RC(6)H(4)N = NC(6)H (4)N = CH-C(6)H(4)OHR = H(2)L(1)的pH,H(2)L(2)的p-Me和H(2)L的p-Cl (3)],是通过水杨醛与2-((邻羟基芳基)偶氮}}苯胺的缩合制备的。H(2)L与VOSO(4)的反应提供了氧钒络合物(L)V(O)(H(2)O)。(L(1))V(O)(H(2)O)络合物在循环伏安法中相对于SCE在0.7 V和-0.65 V下显示两个可逆响应。已经研究了(L(1))V(O)(H(2)O)对H(2)O(2)的催化活性,该反应引起有机硫醚氧化为亚砜和砜。(L(1))V(O)(H(2)O)的细胞毒性也已在人肺癌细胞上进行了检查。
