Copper-catalyzed hydrolysis of bromoisoquinolines: Preparation of hydroxyisoquinolines

A complex phenomenon was observed in the process of preparing hydroxyisoquinoline through copper-catalyzed hydrolysis of bromoisoquinoline. The copper (II) complexes of hydroxyisoquinoline (L2Cu.5H2O) were characterized by high resolution mass spectra, thermogravimetric analysis, IR, 1H nuclear magnetic resonance (NMR), and 2D-NMR. The Cu (II) complexes were mononuclear and coordinated with oxygen and nitrogen atom of two hydroxyisoquinoline and five water molecules in which a strong hydrogen bond was present. Two optimized methods had been studied to prevent the formation of copper (II) complexes. The isoquinoline with 4, 5, 6, 7, and 8 hydroxyl substitutions were successfully prepared by copper-catalyzed hydrolysis of corresponding bromoisoquinoline and then workup by sodium sulfide or adjusted pH by dry ice or carbon dioxide gas.

Excited-State Proton Transfer in Thiazolo-[4, 5-d]thiazo Heterocyclic Systems and the Geometry Alterations’ Effect on Photophysical Characters: A Theoretical Study

Thiazolo-[4,5-d]-thiazo-frame (tztz) compounds are important heteroaromatic organic systems, which recently became a subject of several studies in the field of organic electronics and organic photovoltaics. The most important physical nature of these systems is reported to be an equilibrium between enol and keto forms following excited-state proton transfer. This process originates from a flat trend of the S1 PE (potential energy) profile along the proton transfer coordinate. In the present work, we determined and interpreted the excited-state proton transfer and photophysical nature of these systems extensively by means of the MP2/CC2 and CASSCF theoretical approaches. Also, the effects of amine (-NH2) and cyano (-CN) substitutions were taken into account comprehensively by considering the transition energies and proton transfer pathways of the resulting tztz derivatives. It has been predicted that the physical nature of the excited-state intramolecular proton transfer, as the main character of these systems, is being affected significantly by substitutions. For all of the considered tztz derivatives, a conical intersection (CI) between ground and the S1 excited state was predicted. This CI makes the considered species capable to be responsible for photochromism and photoswitching as well.

Selective, C,C-double bond reduction of alpha,beta-unsaturated carbonyl compounds with cyclohexane using zeolites

Selective ionic hydrogenation of alpha,beta-unsaturated carbonyl compounds with alkanes (cyclohexane and others) was previously known to proceed only in superacidic conditions due to the necessity of dicationic, superelectrophilic activation of the enones. In present paper we disclose that H-form zeolites with acidity well below superacidity, are able however to induce the reduction of alpha,beta-unsaturated carbonyl compounds with cyclohexane in strong analogy to the “parent”, superacid mediated reactions. The probable interpretation of these results in terms of highly electrophilic (superelectrophilic) intermediates on the solid is discussed.

A new interpretation of the ESIPT mechanism of 2-(benzimidazol-2-yl)-3-hydroxychromone derivatives

The present study demonstrates the excited-state intramolecular proton transfer (ESIPT) mechanism of 2-(benzimidazol-2-yl)-3-hydroxychromone (DH3B2) is based on density functional theory (DFT) and time-dependent density functional theory (TDDFT) methods. We find that DH3B2-C is the main conformation to occur ESIPT. Moreover, we get the different results of DH3B2 for the ESIPT mechanisms in comparison with the previous reports. We have optimized three isomers (DH3B2-A, DH3B2-B and DH3B2-C), and calculated absorption and fluorescence spectra, which agree well with the experimental data. Furthermore, we prove the hydrogen bond is enhanced in the S1 state by comparing infrared vibrational spectra, the relevant bond length and bond angle. In our calculations, the results of the three levels of calculations (CAM-B3LYP/TZVP, B3LYP/TZVP and PBEPBE/TZVP) indicate that DH3B2-C is the most stable conformation, by compared the single point energy of three isomers. By constructed the potential energy surfaces (PESs), we find the converted relationship among the three isomers; DH3B2-C is the main conformation in which DH3B2 exists. Furthermore, combination with reduced density gradient (RDG) function, the hydrogen bond of DH3B2-C is stronger than that of DH3B2-A and DH3B2-B, which proves that DH3B2-C form is the most favorable form for ESIPT among the three isomers. Meanwhile, we have further investigated the ESIPT mechanisms of DH3B2, via constructing the potential energy curves (PECs). These results have shown that DH3B2-C is easier to ESIPT occur than DH3B2-A and DH3B2-B. Therefore, the proton receptors of the ESIPT are mainly the benzimidazole nitrogen atoms.
