But the electrochemical results show that complexes exhibitcompletely irreversible redox behaviour which is different from thatfound in diiron proteins. 1.3 To obtain the diiron species which are stable to elec-trochemical reduction, a series of new tetranuclear cage ironspecies containing two 〓 cores, with using hexadentatepolybenzimidazole ligands, were synthesized and characterized by vari-ous spectroscopic methods. Their physical properties have been investi-gated. The crystal structures of 〓〓tetrakis (benzimidazol-2-ylmethyl)-1, 4-diaminobutane and 〓,〓-tetrakis ( N-ethylbenzimidazol-2-ylmethyl )-1, 4-diaminobutane were determined. They contain two 〓 cores which arelinked to each other by -〓-chain in the ligands.

1.3为了获得电化学还原稳定双核氧桥联Fe化合物，使用六齿配体合成了一系列含有两个〓单元四核笼状化合物，并用各种谱学手段表征了它们，还研究了它们的物理化学性质确定了〓L=N，N，N'，N'-四(苯骈咪唑基-1，4-丁二胺和〓，〓四-1，4-丁二胺化合物的晶体结构，它们含有两个〓单元，其中两个〓单元是通过配体的〓链桥联成四核笼状结构。

In addition, we have discovered a new reaction, it is that Dy/SiCl_4 can promote imines to give imidazolidines and tetrasubstituted hydrazines.

Dy／SiCl_4体系具有另外一个重要特性，就是我们发现它能够促进亚胺一步生成五取代的咪唑烷和四取代的肼，这是用其它自由基或直接用稀土金属和亚胺反应无法得到的。

Nickel sulfate was the most frequent sensitizer, followed by Thimerosal, Potassium dichromate, Fragrance mix and Formaldehyde. Frequencies of contact allergy to Thiuram mix, Mercapto mix, Imidazolidinyl urea, and bronopol were relatively low.

结果： 1 129 例受试者中，阳性反应747例，阳性反应率较高的变应原依次是：硫酸镍、硫柳汞、重铬酸钾、芳香混合物、甲醛，阳性反应率较低的变应原有：秋兰姆混合物、硫氢基混合物、咪唑烷基尿素、溴硝丙二醇。

The first step was to synthesize imidazoline. The mole ratio of oleic acid and diethylene triamine was 1:1.2, the xylene was 30%. Temperature was controlled in about 160 ℃ on this stage, timing for acylation reaction was about 1.5 hours.

第一步咪唑啉的合成：油酸和二乙烯三胺摩尔比为1：1.2，以二甲苯为携水剂，反应温度控制在160℃酰化反应1.5小时，然后升温至220℃环化反应，反应时间6.5小时。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
