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.

Abstract The reactions of some aroylhydrazones (HL) with cobalt(II) salts were investigated and chelates of the types [Co(HL) 2 X 2 ] and [Co(L) 2 ] were isolated. Analytical data, infrared studies, magnetic moments and solution spectra as well as some conductivity measurements were used to characterise these chelates. The [Co(HL) 2 X 2 ] chelates were found to possess octahedral configuration in solid
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。

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
