Tribochemically active chelate complexes of salicylideneimines
摘要:
N-Alkylsalicylideneimines and their complexes with 3d metals were obtained by chemical (from metal salts) and electrochemical methods (from metals in the zero oxidation state). The compounds obtained were characterized by IR and H-1 NMR spectroscopy and X-ray diffraction analysis. According to crystallographic data, nickel bis(chelate) exists in the trans-planar configuration. A friction test revealed that the tribotechnical characteristics of lubricating formulations are substantially enhanced in the presence of N-alkylsalicylideneiminates.

Twelve copper(II) Schiff base complexes derived from lipophilic amines have been prepared using either salicylaldehyde or ortho-vanillin via a microwave-assisted reaction. All complexes have been obtained elementally pure and an X-ray diffraction of an isopentyl derivative has confirmed the structure of these compounds. All complexes showed a promising degree of anti-mycobacterial activity against
已经使用水杨醛或邻香兰素通过微波辅助反应制备了十二种衍生自亲脂胺的铜 (II) 席夫碱配合物。所有配合物均已获得元素纯,异戊基衍生物的 X 射线衍射证实了这些化合物的结构。所有复合物都显示出对结核分枝杆菌的有希望的抗分枝杆菌活性,其中活性似乎随着脂肪链长度的增加而增加。
