由2-吡啶甲醛与N-对甲苯磺酰基-1，2-二氨基苯反应合成了N-甲苯磺酰-1，2-二氨基苯。L1
曾经是
具有结晶学特征的。检查了L1与镍中心的相互作用。电化学法
镍与L1和N-(2-羟基苯基)水杨酰亚胺(H_2L4)相互作用生成NiL_1L_4·2H_2O_1
二氯甲烷重结晶分离出NiL32·0.75H2O_2(HL3=1-[(4-methylphenyl)sulfonamido]-2-[1-(2-pyridylmethylidene)amino]benzene)，单晶
其中L1经历了重排。
在L1与镍和对甲苯磺酸在电化学池中的反应中，分离出了配合物2
作为大宗产品。用元素分析、红外光谱和磁学方法对镍配合物进行了表征
测量。用单晶X-射线衍射法测定了2的分子结构。
Two
different compounds, L1
{3-[ethoxy(2-pyridyl)methyl]-1-[(4-methylphenyl)sulfonyl]-2-(2-pyridyl)-2,3-dihydro-1H-benzo[d]imidazole} and L2
{1-[(4-methylphenyl)sulfonyl]-2-(2-pyridyl)-2,3-dihydro-1H-benzo[d]imidazole}
have been synthesised by the reaction of 2-pyridinecarboxaldehyde with N-tosyl-1,2-diaminobenzene. L1
was
crystallographically characterised. The interaction of L1 with a nickel centre was checked. Electrochemical
interaction of Ni with L1 and N-(2-hydroxyphenyl)salicylidenimine (H2L4) produces NiL1L4·2H2O 1. Its
recrystallisation in dichloromethane leads to the isolation of single crystals of NiL32·0.75H2O 2 (HL3=1-[(4-methylphenyl)sulfonamido]-2-[1-(2-pyridylmethylidene)amino]benzene),
where L1 underwent a rearrangement.
In the reaction of L1 with Ni and p-toluenesulfonic acid in an electrochemical cell, complex 2 is isolated
as the bulk product. Nickel complexes have been characterised by elemental analysis, IR spectroscopy and magnetic
measurements. The molecular structure of 2 has been determined by single X-ray diffraction studies.
