Novel compositions of matter based on homopiperazine precursor materials and forming a homopiperazine-based ligand are disclosed, along with suitable techniques and materials for the synthesis and utilization thereof. In particular various synthetic schemes and techniques for applying the disclosed compositions of matter as a decontaminating agent. The decontaminating agents include homopiperazine-based ligand-metal complexes that are particularly effective at neutralizing toxicity of nerve agents, pesticides, and other toxic organophosphorus-based compounds. In preferred approaches, the homopiperazine-based ligand-metal complexes act as catalysts to facilitate substitution of a leaving group of the organophosphorus-based compound with a functional group that does not permit the organophosphorus-based compound to inactivate acetylcholinesterase upon introduction of the organophosphorus-based compound to a living organism such as insects and mammals. Advantageously, the catalytic homopiperazine-based ligand-metal complexes are formed using inexpensive, readily-available precursor materials, and may be utilized to neutralize toxins without relying on damaging caustic reactants or environmentally unfriendly organic solvents.
基于同环异丙二胺前体材料的新型物质组合物以及形成基于同环异丙二胺的配体的方法被披露,还有适用的合成和利用技术和材料。特别是各种合成方案和技术,用于将披露的物质组合物作为除污剂。这些除污剂包括基于同环异丙二胺配体-金属配合物,特别有效地中和神经毒剂、杀虫剂和其他有机磷基化合物的毒性。在首选方法中,基于同环异丙二胺的配体-金属配合物作为催化剂,促进有机磷基化合物的脱离基团被一个功能基团替代,该功能基团不允许有机磷基化合物在引入有机磷基化合物到昆虫和哺乳动物等生物体时使乙酰胆碱酯酶失活。优点是,这种催化同环异丙二胺基配体-金属配合物是使用廉价、易得的前体材料形成的,并且可以用于中和毒素,而不依赖于有害的腐蚀性反应物或环境不友好的有机溶剂。
