chelating ligand, abbreviated as PS-teta (PS = polymeric support), reacts with metal chlorides (Cu2+, Co2+, and Ni2+) in methanol to give polymer-bound transition metal complexes, PS-Cu(II)teta/(Cat-1), PS-Ni(II)teta/(Cat-2), and PS-Co(II)teta/(Cat-3), formation of which has been established by various physiochemical methods and spectroscopic techniques. The catalytic potential of these materials has
从三亚乙基四胺和水杨醛获得的四齿席夫碱 (teta) 已与二乙烯基苯交联的氯甲基化聚苯乙烯共价键合。这种螯合配体,缩写为 PS-teta(PS = 聚合物载体),在甲醇中与金属氯化物(Cu2+、Co2+ 和 Ni2+)反应生成聚合物结合的过渡金属配合物 PS-Cu(II)teta/(Cat- 1)、PS-Ni(II)teta/(Cat-2) 和 PS-Co(II)teta/(Cat-3),其形成已通过各种物理化学方法和光谱技术确定。这些材料的催化潜力已经在 30% H2O2 作为氧化剂的情况下测试了各种烯烃、烷烃、醇和硫醚的氧化。同时,
