We report the synthesis and the spectroscopic and electrochemical properties of six mononuclear iridium(iii) and ruthenium(ii) complexes bearing S,S?-extended phenanthroline ligands. Starting from 5,6-dibromide-1,10-phenanthroline, the dithiine derivatives N,N?-1,10-phenanthrolinedithiino[2,3-b]quinoxaline and N,N?-1,10-phenanthrolinedithiino[2,3-b]benzene were prepared by primary N,N?-complexation of the dibromo derivative and subsequent nucleophilic substitution at the complex. The photoluminescence of the phenanthroline-dithiine containing complexes shows distinctively increased lifetimes for all Ir(iii) and Ru(ii) complexes. The activity of the series of Ir(iii) and Ru(ii) complexes as photosensitizers in visible-light photocatalytic water reduction is demonstrated by dihydrogen evolution with a [Fe3(CO)12] catalyst and triethylamine as a sacrificial donor.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. HPLC of Formula: C8H4Cl2N2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 2213-63-0, in my other articles.

Substituted dihydroquinozalin-2-ones (1-16) have been synthesized easily by the use of copper-catalyzed coupling method. The reactions of 2-haloanilines with a variety of alpha-amino acids in the presence of copper (I) iodide gave corresponding 3-substituted dihydroquinozalin-2-ones in up to 86% yield. Some new quinoxalin-2-ones (2, 4, 5, 13 and 16) have moderate cytotoxic activity toward HeLaS3 cell lines at 4.9-18.1 muM.

(Chemical Equation Presented) Bisvelcrand 3 based on resorcin[4]arene was obtained by a stepwise route, and the formation of oligobisvelcraplex 3 n by solvophobic pi-pi stacking interaction was observed. 1H NMR spectroscopic studies revealed that DeltaG ?pSeudorotation of oligobisvelcraplex 3n is 16.7 kcal mol-1 in C6D5NO2 solution. The pulsed field gradient spin-echo (PGSE) NMR experiment and VPO experiment showed that the number of aggregation (n) ranges from 7 to 10 in CHCl3 solution at 298 K. In high concentration, bisvelcrand 3 tends to form gels or fiber.

An inexpensive, practical and one-pot method has been developed for the synthesis of quinoxalines fused with pyrano[3,4-b]indole, the central core of Lamellarin D. The methodology involved construction of the central pyranone ring via an AlCl3-mediated heteroarylation-cyclization method. A number of compounds were prepared using this methodology, some of which were converted to the corresponding indol-3-ylquinoxaline derivatives. Several of the pyrano[3,4-b]indole fused quinoxalines showed promising growth inhibition of cervical and lung cancer cells and good interactions with topoisomerase I in silico.
