A simple and easily synthesis of new generation of N-donor bipyrazolic tripods by coupling of functionalized pyrazole derivatives and an appropriate primary amine derivative via condensation or nucleophilic substitution reaction is presented. The complexation capacity of these compounds towards bivalent metal ions (Hg2+, Cu2+, Pb2+, Cd2+) and alkaline metal ions (Li+, Na+, K+) were investigated using
通过官能化的吡唑衍生物和适当的伯胺衍生物通过缩合或亲核取代反应的偶联,简单而容易地合成了新一代的N-供体双吡唑三脚架。利用液-液萃取法研究了这些化合物对二价金属离子(Hg 2 +,Cu 2 +,Pb 2 +,Cd 2+)和碱金属离子(Li +,Na +,K +)的络合能力。。提取的百分比极限通过原子吸收测量确定。
