摘要研究了某些芳香酰hydr(HL)与钴(II)盐的反应,并分离了[Co(HL)2 X 2]和[Co(L)2]类型的螯合物。使用分析数据,红外研究,磁矩和溶液光谱以及一些电导率测量来表征这些螯合物。发现[Co(HL)2 X 2]螯合物在固态下具有八面体构型,但在DMF溶液中解离。试图鉴定解离产物。暂时为中性[Co(L)2]螯合物指定了一个二聚体五坐标结构。
Routes for the selective synthesis of 1-, or 2-substituted hydrazides, and 1,2-disubstituted hydrazides are reported. These routes proceed via cyanoborohydride reduction of stable acyl hydrazone intermediates.
Provided herein are compounds of the formula (1):
as well as pharmaceutically acceptable salts thereof, wherein the substituents are as those disclosed in the specification. These compounds, and the pharmaceutical compositions containing them, are useful for the treatment of diseases such as, for example, obesity, type II diabetes mellitus and metabolic syndrome.

neutral bis(ligand)nickel(II) chelates derived from some bidentate aroylhydrazones have been prepared and characterized. Whatever the solubility permits, the reaction of the neutral bis-(ligand)chelates, NiL 2 , with some heterocyclicbases were studied spectrophotometrically in benzene solution. The stability constants as well as the thermodynamic parameters (ΔG, ΔH, ΔS) for the adduct formation reaction
