以3,4-二甲基苯酚和相应的胺为原料，在甲醛存在下，采用微波诱导技术合成了新型酚类曼尼希碱2,2′-（2-羟基-4,5-二甲基苄基）二乙醇（1)和2-（2-（4（2-羟基-4,5-二甲基苄基）哌嗪-1-基）乙胺）甲基）-4,5-二甲基苯酚(2)，产率较高。还制备了Ni(II)（3和5）和Cu(II)（4和6）的金属配合物1和2，并通过元素和光谱分析对所有化合物进行了表征。金属配合物的热、磁和电子研究也有报道。电子能谱和磁化率测量表明，Ni(II)(3)配合物为四面体，Cu(II)(4)配合物为平面正方形1，Ni(II)(5)和Cu(II)(6)配合物均为八面体2。
The novel phenolic Mannich bases 2,2'-(2-hydroxy-4,5-dimethylbenzylazanediyl) diethanol (1) and 2-((2-(4( 2-hydroxy-4,5-dimethylbenzyl)piperazin-1-yl)ethylamino)methyl)-4,5-dimethylphenol (2) have been synthesized in good yield by using a microwave-induced technique from 3,4-dimethylphenol and corresponding amines in the presence of formaldehyde. Metal complexes of 1 and 2 for Ni(II) (3 and 5) and for Cu(II) (4 and 6) have also been prepared and all compounds have been characterized by elemental and spectral analyses. Thermal, magnetic, and electronic studies have also been reported for metal complexes. Electronic spectra and magnetic susceptibility measurements suggested tetrahedral geometry for Ni(II) (3), square planar geometry for Cu(II) (4) complexes of 1, and octahedral geometries for both Ni(II) (5) and Cu(II) (6) complexes of 2.
