After coupling diazotized p-chloroaniline with imidazole, the resulting monoazo dye is quaternized with dimethyl sulfate. Upon dimethylamination, the ...

对-氯苯胺重氮化后，与咪唑偶合，生成单偶氮染料，与硫酸二甲酯季铵化，所得季铵化合物再经二甲胺基化即为题示染料。

The electron impact mass spectra of noncyclic crown ether s with heterocyclic methmazole as terminal groups 1a￣4a and fo were given and discussed in the present article.

本文给出以杂环甲巯咪唑为端基的非环冠醚1a～4a及1a的异构体1b的电子轰击质谱并讨论之。

In the thesis, a series of novel single and multi-armed oxadiazole bridging ligands and pyridyl-4, 5-imidazole dicarboxylic acid ligands have been synthesized. The coordination chemistry of these novel ligands with transition metal ions was investigated. In addition, two 1, 3, 4-oxadiazole bridging ligands end-capped by chelating Schiff-base coordination sites have been designed and synthesized. The coordination chemistry based on one of the two ligands with metal ions was primarily investigated.

本文报道了一系列新颖的含1， 3， 4-Oxadiazole杂环的单臂及多臂有机配体，研究了它们与过渡金属离子的配位反应化学；合成了吡啶基-4，5-咪唑二羧酸有机配体，研究了它们在水热条件下与过渡金属离子的配位反应化学；另外，还合成了1， 3， 4-Oxadiazloe杂环桥联的双Schiff-base有机配体，初步探讨了其与过渡金属离子的配位反应化学。

During the process of imidacloprid preparation, using phosphorus pentachloride dehydration and greatly excess 2-nitroiminoimidazolidine, the yield may reach 90%, and the purity is over 95%, so this a fairly good synthesis method.

吡虫啉合成中用五氧化二磷脱水法和过量2-硝基亚氨基咪唑烷法收率接近90%，纯度达95%以上，是较佳的合成方法。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
