Gaussian electronic properties studies of organic materials based on pyridazine for efficient photovoltaic devices

Gaussian quantum calculations are performed to optimize geometries and obtain properties depending on the electronic and photovoltaic for some pyridazine derivatives: 6-methylpyridazin-3(2H)-one (MPYO), 6- phenylpyridazin-3(2H)-one (PPYO), 6-phenylpyridazin-3(2H)-thione (PPYS) and 5-(4-chlorobenzyl)-6- methylpyridazine-3(2H)-thione (CBMPYS). These novel four organic donor-pi-acceptor dyes (D-pi-A), used for dyesensitized solar cells (DSSC), based on pyridazine were studied by density functional theory (DFT) approaches to shed light on how the pi-conjugation order influence the performance of the dyes. The theoretical results have shown that the polarizable continuum model (PCM) were reasonably capable of predicting the excitation energies, the absorption and the emission spectra of the molecules. The HOMO and LUMO energy levels of these dyes can ensure a positive effect on the process of electron injection and dye regeneration. The trend of the calculated deltaEg gaps nicely compares with the spectral data. Key parameters in close connection with the short-circuit current density (Jsc), including light-harvesting efficiency (LHE), injection driving force (deltaGinject) and total reorganization energy (?total) were discussed. In addition, the estimated values of open-circuit photovoltage (Voc) for these dyes were presented. The calculated results of these dyes reveal that the PPYS can be used as a potential sensitizer for TiO2 nanocrystalline solar cells due to its best electronic and optical properties and good photovoltaic parameters.

Convenient preparation of 3-methoxycarbonylpyridazines by palladium catalyzed alkoxycarbonylation of pyridazinetriflates

The methoxycarbonylation of several pyridazine-trifluoromethanesulphonates with CO and MeOH is catalyzed by Pd(OAc)2 and 1,1?-bis(diphenylphosphino)ferrocene. This method constitutes a mild and efficient homologation of pyridazinones.

Novel pyridazine based scorpionate ligands in cobalt and nickel boratrane compounds

Heating of 6-methylpyridazine-3-thione (HPnMe) and 6-tert-butylpyridazine-3-thione (HPntBu) with potassium borohydride in diphenylmethane in a 3:1 ratio gave two new scorpionate ligands K[HB(Pn Me)3] and K[HB(PntBu)3]. Single crystal X-ray diffraction analysis of the methyl derivative K[HB(Pn Me)3] revealed a dimeric species with one potassium atom coordinated by six sulfur atoms of two scorpionate ligands and a second potassium atom coordinated by three nitrogen atoms of one of the two ligands as well as by three water molecules. The reaction of K[HB(PntBu) 3] with nickel(II) chloride or cobalt(II) chloride in CH 2Cl2 led to the new boratrane compounds [M{B(Pn tBu)3}Cl] (M = Ni 1, Co 3) where a formal reduction of the metal ions to Ni(I) and Co(I), respectively, and activation of the B-H bond occurred. Similar reactivity was observed by employing K[HB(PnR) 3] (R = Me, tBu) and nickel(II) chloride in water. Reaction with cobalt(II) chloride in water also gave boratrane compounds [Co{B(Pn R)3}(PnR)] (R = tBu 4, Ph 5), but instead of a chloride a bidentate pyridazinethionate ligand from a defragmentated scorpionate is found in the molecules. The molecular structures of all nickel and cobalt compounds were determined by single crystal X-ray diffraction analyses confirming the formation of boratranes in compounds 1-5. Magnetic measurements confirm the reduced oxidation states and the paramagnetic character of the Ni(I) and Co(I) complexes. Supportive DFT studies were carried out for a better understanding of the electronic nature of the metal-boron bond of the boratrane complexes.

Nitrile oxide [3+2] cycloaddition: Application to the synthesis of 6-substituted 3(2H)-pyridazinones and 6-substituted 4,5-dihydro-4-hydroxy-3(2H)-pyridazinones

An efficient method for the preparation of 6-substituted 3(2H)-pyridazinones and 6-substituted 4,5-dihydro-4-hydroxy-3(2H)-pyridazinones starting from 3,5-disubstituted 4,5-dihydroisoxazoles is described. N-O bond cleavage of the isoxazoline ring promoted by molybdenum hexacarbonyl or by catalytic hydrogenation afforded the alpha-hydroxy gamma-keto esters 4a-f which were converted into 6-substituted 4,5-dihydro-4-hydroxy-3(2H)-pyridazinones 5a-f or 6-substituted 3(2H)-pyridazinones 6a-f on treatment with hydrazine hydrate at room temperature or reflux in high yield starting from 4a-f. The flexibility of this protocol has been demonstrated by the synthesis of the C-nucleoside 7 starting from the known beta-ribofuranosylnitromethane 8. Moreover, an intramolecular version of this methodology has been developed to prepare the known antiulcer tricyclic 3(2H)-pyridazinone 12.
