Two new classes of heteroacenes, namely benzo[4′,5′]thieno[2′,3′:4,5]thieno[3,2-b]quinolines and benzo [4′,5′]thieno[2′,3′:4,5]thieno[3,2-b][1,8]naphthyridines, have been formed using the Friedlander reaction to annulate the benzo[b]thieno[2,3-d]thiophene scaffold to quinoline or 1,8-naphthyridine fragments. In accordance with this synthetic strategy, benzo[b]thieno[2,3-d]thiophen-3(2H)-ones were treated with 2-aminobenzaldehydes or 2-aminonicotinaldehyde in the presence of pyrrolidine in glacial acetic acid at reflux to give the desired quinoline- or 1,8-naphthyridine-fused compounds, respectively. The optical and electrochemical properties of selected heteroacenes were determined. (C) 2019 Elsevier Ltd. All rights reserved.

Well-defined dinuclear silver(I) complexes have been targeted for applications in catalysis and materials chemistry, and the effect of close silver-silver interactions on electronic structure remains an area of active inquiry. In this study, we describe the synthesis, structure, and photophysical properties of dimeric silver complexes featuring a redox-active naphthyridine diimine ligand. Unusually for silver(I), these complexes display absorption features in the visible region due to metal-metal to ligand charge transfer (MMLCT) transitions, which arise from the combination of close silver-silver interactions and low-lying ligand pi* orbitals. The complexes’ photophysical properties are explored via a combination of spectroscopic and computational studies, revealing MMLCT excited state lifetimes that exceed 1 mu s. These results portend previously unforeseen applications of silver(I) dimers in visible light absorption and excited state reactivity.

Two unprecedented, homoleptic Pt-1,8-naphthyridine complexes have been prepared and characterized. Reaction between 1,8-naphthyridine (napy) and a platinum(II) precursor leads to a mononuclear homoleptic platinum(II) complex with stoichiometry [Pt(napy)(4)](OTf)(2). On the contrary, reaction between napy and a dinuclear platinum(III) precursor produces instead a rare example of a dinuclear, homoleptic, tetracationic platinum(II) complex with stoichiometry [Pt-2(napy)(4)](OTf)(4). Crystal structures of both complexes have been obtained. The redox behavior of the dinuclear complex has been studied by cyclic voltammetry, in order to establish its suitability as model precatalyst for organometallic reactions exploiting the Pt(II)/Pt(IV) or Pt(II)/Pt(III) manifold.

Helical structures were constructed by using pi-spacer-bridged dimers of dibenzopyrrolo[1,2-a][1,8]naphthyridine, which has a highly fluorescent L-shaped pi-extended skeleton. Three dimers with biphenylene (dimer 1), phenanthrene (dimer 2), and m-phenylene (dimer 3) spacers, as well as a fixed-helical dimer 4 where two quinolone rings were covalently cross-linked, were designed and prepared. H-1 NMR and ROESY spectra revealed that dimers 1 and 2 adopted helical forms in solution, whereas dimer 3 did not. The helical conformation of 1 was strengthened by addition of either polar or nonpolar solvents to the chloroform solution, which suggested that pi-pi stacking was the main contributor to the stabilization of the helical structure. All of the dimers, including fixed-helical dimer 4, emitted fluorescence with high quantum yields (phi=0.79-0.86).

The kinetics of association of ureido-pyrimidinone (U) dinners, present either in the 4[1H]-keto form or in the pyrimidin-4-ol form, with 2,7-diamido-1,8-naphthyridine (N) into a complementary heterodimer have been investigated. The formation of heterodimers with 2,7-diamido-1,8-naphthyridine from pyrimidin4-ol dimers is much faster than from 4[1H]-pyrimidinone dimers. Using a combination of simple measurements and simulations, evidence for a bimolecular tautomerization step is presented. Finally, the acquired kinetic knowledge of the different pathways leading from ureido-pyrimidinone homodimers to ureidopyrimidinone:diamido-naphthyridine (U:N) heterodimers allows the prediction and observation of kinetically determined ureido-pyrimidinone heterodimers which slowly convert back to the corresponding homodimers.

In conclusion, we affirm that quantitative kinetic descriptions of catalytic behavior continue to serve as an indispensable tool to navigate research efforts intended to model and predict the effects of solvation within porous materials, I hope to 94839-07-3 help many people in the next few years.

4-Ethyl-3-formyl-2,6-diphenylpyrylium perchlorate was obtained from 2,6-diphenylpyrylium perchlorate in three steps. Its reaction with triethyl orthoformate was accompanied by rearrangement of the initial pyrylium ring and led to pyrano[3,4-c] pyran-7-ium perchlorate system through a domino process involving ethanol addition-elimination. A plausible mechanism of the reaction is suggested on the basis of DFT quantum-chemical calculations. Reaction of the obtained pyrano[3,4-c] pyran-7-ium perchlorate with ammonium acetate led to a 2,7-naphthyridine derivative without a skeletal rearrangement.

Alternating pi-conjugated copolymers of 1,8-naphthyridine-2,6-diyl (1,8-Nap) with 9,9-dioctylfluorene-2,7-diyl (P(Flu-Ph-1,8-Nap)) and 2,5-didodecyloxy-1,4-phenylene (P(ROPh-Ph-1,8-Nap)) have been synthesized by Pd-catalyzed organometallic polycondensation. The copolymers showed UV-vis absorption peaks at around 390 nm in o-dichlorobenzene. The polymers were photoluminescent both in o-dichlorobenzene and in the solid state. In o-dichlorobenzene, the emission peaks of P(Flu-Ph-1,8-Nap) and P(ROPh-Ph-1.,8-Nap) appeared at lambda(EM) = 440 and 471 nm, with quantum yields of 87% and 66%, respectively. Electrochemical data revealed that 1,8-Nap behaved as a typical electron-accepting unit. When P(Flu-Ph-1,8-Nap) was treated with 10-camphorsulfonic acid, the emission peak shifted to lambda(EM) = 598 nm. (C) 2011 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 49: 4204-4212, 2011

Oxazoline and camphor-pyrazole units are introduced on the 1,8-naphthyridine scaffold to access chiral ligands L-1, L-2 and L-3. Metalation of these chiral ligands with Cu(I) and Ag(I) precursors afforded di- and tetranuclear complexes [Cu4I4(L-1)(2)] (1), [Cu4I4(L-2)(2)] (2), [Cu2I2(L-3)] (3), [Cu2I(L-2)(2)](OTf) (4), [Ag-2(L-1)(2)](OTf)(2) (5) and [Ag-4(L-2)(4)Br](OTf)(3) (6), containing [M4Xn] (n= 1,4 and X = Br, I) or [M2Xn] (n = 0, 1, 2 and X = I) core. All complexes are structurally characterized. Naphthyridine-derived ligands reveal bridge-chelate coordination motif and hold two metal centers in close proximity. The tetranuclear complexes are dimer of dinuclear complexes bridged by the halides. Electronic absorption and emission spectra of copper complexes are reported. Catalytic utility of all complexes are examined for asymmetric transformations but they showed poor activity probably due to limited solubility and coordinative saturation at the metal centers. The best results are obtained with [L-3/Cu salt] combination for cyclopropanation of styrene, N-H bond insertion and nitroaldol (Henry) reactions with very low enantioselectivity.
