合成了邻氯苯甲醛与O，S-二甲基磷酰亚胺缩合得到的席夫碱及其Cu（Ⅱ），Ni（Ⅱ），Zn（Ⅱ），Co（Ⅱ）配合物．用元素分析，IR，UV，摩尔电导等对所合成化合物进行了测试，配体还采用MS和1HNMR进行了表征，确定了这些化合物的组成和配位状态，还对化合物进行了蚜虫和红蜘蛛的生测实验以及抑制超氧阴离子自由基活性的研究．
Schiff bases and their Cu (Ⅱ), Ni (Ⅱ), Zn (Ⅱ) and Co (Ⅱ) complexes were synthesized by the condensation of o-chlorobenzaldehyde with O, S-dimethylphosphoramidite. The synthesized compounds were characterized by elemental analysis, IR, UV and molar conductance. The ligands were characterized by MS and 1HNMR. The composition and coordination state of these compounds were determined. Aphids and spider mites Of the bioassay experiments and inhibition of superoxide anion free radical activity.
