A facile synthesis of chromonyl & quinolinyl 1,2,4-s-triazolo [4,3-a] quinoxalines by dehydrogenative cyclization using DDQ

A series of chromonyl and quinolinyl 1.2.4-s-triazolo(4,3-a) quinoxalines (6 and 7) have been prepared by dehydrogenative cyclization of schiff’s bases (3 and 5) derived from 2-chloro-3-hydrazinoquinoxlines (1) and 3-formylchromone (2) and 2-chloro-3-formylquinolines (4) using DDQ.

Conformational analysis of mixed oxathia crown ethers and their complexational ability towards Ag(I) and Pd(II) – An experimental solution NMR and theoretical molecular modelling study

Both the conformation and flexibility of four mixed oxathia crown ethers and their Ag(I) and Pd(II) complexes were studied by 1H NMR (delta5, J, NOE, T1), 13C NMR, dynamic 1 NMR spectroscopy and molecular modelling. The stoichiometry and stability constants of the complexes were determined from corresponding Job’s plots in the case of Ag(I) complexes as the interchange between free and complexed states was fast on the NMR timescale; interchange for the Pd(II) complexes was sufficiently slow such that distinct sub-spectra were observable for the free and complexed states. In all cases where complexation was observed, 1:1 complexes were formed. Global minima structures determined from the modelling studies were analysed with respect to the barriers to ring interconversion, the flexibility of the species in solution and the preferred complexation of Ag(I) and Pd(II) to the sulfur atoms of the crown ethers.

Synthesis and Characterization of Azine-[5]Helicene Hybrids

Novel azine-helicene hybrids (pyridine-, pyrazine- and quinoxaline-fused along the central ring [5]helicenes) have been prepared in good overall yields through a five-step synthetic sequence. Commercially available 2,3-dihaloazines were used as starting materials. To discern the effect of merging an azine moiety within a helical skeleton, the X-ray structures, UV/Vis absorption spectra, cathodic and anodic electrochemistry of the helicene hybrids were investigated and compared to that of the parent [5]helicene.
