Graphical Abstract: Directed synthesis of dianiline- (DAnH2) and disulfanilamideglyoximes (DSamH2) has been accomplished by condensation of dichloroglyoxime with aniline or sulfanilamide in 1:2 molar ratio, as well as their corresponding Co(III), Ni(II) and Cu(II) coordinative compounds. Composition, structure and some properties of dioximes and complexes have been established by using elemental analysis, UV-Vis, IR and NMRspectroscopies. Dioxime coordination at the central atom and structure of complexes depends on pH of reaction medium: at pH=5-6 - bis-dioximates, whilst at pH=2 – tris-dioximines are obtained.

Abstract (JPEG)

DOI: dx.doi.org/10.19261/cjm.2009.04(2).06

Graphical Abstract: Substituted indolizines are very attractive heterocyclic units. On developing efficient methods toward differently substituted indolizines, we were particularly interested in elaborating efficient approaches toward three-component reaction of these compounds which are very interested from the point of view fluorescent properties. The microwave-mediated three component reaction of acyl bromide, bipyridine and dipolarophyl is catalyzed by basic alumina to give corresponding bis-indolizines in excellent yields in a one –pot reaction.

Graphical Abstract: A Schiff base macrocycle with persistent rhomboidal shape was synthesized in excellent yield through [2+2] condensation reaction between (R,R)-1,2-diaminocyclohexane and 4,4’-diformyltriphenylamine. The dimeric macrocylic structure was proved by electrospray ionization mass spectrometry (ESI-MS), 1H-NMR, and FTIR spectroscopy. The complexation properties were evidenced by UV absorption.
