Synthesis and characterization of polyaromatic azine derivatives of (eta5-C5H5) Fe(CO)2 and (eta5-C9H7) Fe(CO)2

The synthesis and characterization of 14 monometallic derivatives of quinoline, quinoxaline, quinazoline and tetraazolo<1,5-A>quinoline and a bimetallic derivative of quinoxaline are reported. These species were prepared in 11 to 88% isolated yields by metathesis reactions between NaFp or NaFp? (where Fp = (eta5 – C5H5)Fe(CO)2 and Fp? = (eta5 – indenyl)Fe(CO)2 ) and the appropriate chlorine substituted polyaromatic azines. These reactions are highly regioselective and generally produce a single organometallic product having the organometallic substituent(s) bonded to the more highly activated azine ring. The structures of three representative examples were confirmed by their X-ray crystal structures, which are reported for the title complexes 4-[(eta5-cyclopentadienyl)irondicarbonyl]-7-chloroquinoline (C16H10ClFeNO2; a = 7.608(1)A, b = 12.006(1)A, c = 15.664(1)A, V = 1431A3; orthorhombic; P212121; Z =4), 2-[(eta5-cyclopentadienyl)irondicarbonyl]-3-chloroquinoxaline (C15H9ClFeN2O2; a = 15.291(3) A, b = 6.561(2) A, c = 14.541(4) A, beta = 106.891(21), V= 1395.9A3; monoclinic; P21/c; Z = 4), and 2-[(eta5-indenyl)irondicarbonyl]-3-chloroquinoxaline (C19H11ClFeN2O2; a = 19.131(2)A, b = 6.688(1)A, c = 13.515(2) A, beta= 101.569(11), V = 1694.1 A3; monoclinic; P21/c; Z = 4). The bimetallic quinoxaline derivative 2,3-[(C5H5)2Fe2(CO)4]-quinoxaline has orrto-substituted organometallic groups and the spectroscopic data suggest that it has an unusual structure in solution, perhaps involving bridging cyclopentadienyl and carbonyl ligands.

A New Route to Indolo<3,2-b>isoquinolines

2-Phenylindole-3-carbaldoximes (2a-d) on cyclization with alcoholic sulphuric acid give delta-carbolines, indolo<3,2-b>-isoquinolines (5a-d) and not the gamma-carbolines.This constitutes a new route to delta-carbolines.

Computational and electrochemical analysis on quinoxalines as corrosion inhibitors for mild steel in acidic medium

In this investigation, quinoxaline derivatives namely, 2-(5-(2-chlorophenyl)-3-phenyl-4,5-dihydro-1H-pyrazol-1-yl)naphtho[2,3-d]thiazole (CPTQ) and 2-(3,5-diphenyl-4,5-dihydro-1H-pyrazol-1-yl)naphtho[2,3-d]thiazole (DPTQ) were synthesized and applied as corrosion inhibitors for mild steel (MS) in15% HCl solution. The corrosion inhibition behaviour of CPTQ and DPTQ was studied through weight loss measurement, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). The maximum corrosion inhibition efficiency of DPTQ and CPTQ was found to be 96.01 and 95.62%, respectively at 100 ppm concentration and 303 K temperature. Potentiodynamic polarization studies showed that CPTQ and DPTQ act as mixed type inhibitors. Surface morphology of uninhibited and inhibited MS specimens was characterized using AFM and SEM studies. DFT, molecular dynamic simulations and calculation of Fukui functions were performed for correlation of theoretical parameters with the experimental results.

Dramatically enhanced fluorescence of heteroaromatic chromophores upon insertion as spacers into oligo(triacetylene)s

In continuation of a previous study on the modulation of pi-electron conjugation of oligo(triacetylene)s by insertion of central hetero-spacer fragments between two (E)-hex-3-ene-1,5-diyne ((E)-1,2-diethynylethene, DEE) moieties (Fig. 1), a new series of trimeric hybrid oligomers (14-18 and 22-24, Fig. 2) were prepared (Schemes 1-3). Spacers used were both electron-deficient (quinoxaline-based heterocycles, pyridazine) and electron-rich (2,2?-bithiophene, 9,9-dioctyl-9H-fluorene) chromophores. With 19-21 (Scheme 4), a series of transition metal complexes was synthesized as potential precursors for nanoscale scaffolding based on both covalent acetylenic coupling and supramolecular assembly. The UV/VIS spectra (Fig. 3) revealed that the majority of spacers provided heterotrimers featuring extended pi-electron delocalization. The new hybrid chromophores show a dramatically enhanced fluorescence compared with the DEE dimer 13 and homo-trimer 12 (Fig. 5). This increase in emission intensity appears as a general feature of these systems: even if the spacer molecule is non-fluorescent, the corresponding hetero-trimer may show a strong emission (Table 2). The redox properties of the new hybrid chromophores were determined by cyclic voltammetry (CV) and rotating-disk voltammetry (RDV) (Table 3 and Fig. 5). In each case, the first one-electron reduction step in the hetero-trimers appeared anodically shifted compared with DEE dimer 13 and homo-trimer 12. With larger spacer chromophore extending into two dimensions (as in 14-18, Fig. 2), the anodic shift (by 240-490 mV, Table 3) seems to originate from inductive effects of the two strongly electron-accepting DEE substituents rather than from extended pi-electron conjugation along the oligomeric backbone, as had previously been observed for DEE-substituted porphyrins.
