The complex RuCl2(PPh3)3 (1) showed to be an efficient and regioselective precatalyst for the hydrogenation of quinoline (Q) to 1,2,3,4-tetrahydroquinoline (THQ) at P = 5.0–6.5 at m and T = 140−167 °C. This reaction showed to be first order on c

The partial molar volumes of indole(Ind) at infinite dilution (\(V_{2}^{\infty}\)) in carbon tetrachloride (CCl4), acetonitrile (ACN) and tetrahydrofuran (THF) as solvents, were estimated from densitometry measurements at 293.15 K. The results indica

The linear (α), and nonlinear (β, γ) optical NLO properties of ortho-, meta- and para-nitrophenol (ONP, MNP and PNP) isomers have been calculated in gas phase by using ab initio (HF, MP2 and MP4) and density functional theory (DFT) (B3LYP, CAM-B3L

A study of the ground and the first five electronic excited singlet states properties of urea and thiourea molecules is reported. Our interest lies on structural features (bond distances and angles), electronic behavior (energy, dipole moment, charge

In order to carry out a comparison, the hydroformylation of 1-hexene to their corresponding aldehydes (heptanal and 2-methyl-hexanal) was studied both under syngas conditions and with paraformaldehyde using the catalytic rhodium/diphosphine precataly

The interaction of ethanethiol (C 2 H 5 SH) with a model cluster of three tetrahedral zeolite sites (T3) and a larger zeolite model represented by a 12-membered ring with one hydroxyl Bronsted acid site (T12), has been investigated by Hartree–Fock

We have investigated theoretically the interaction of cis -2-butene with a Bronsted acid site (BAS) embedded within a ring of 10 tetrahedral zeolite cluster (T10-OH). Calculations were performed at ab Initio SCF-MO level with the STO-3G basis set. Cs

In the present work, we report a theoretical study about the interaction between the NO molecule and the Z–CuO zeolite. The zeolite was modeled with the H 3 Si(OCuO)AlH 3 (B 1 CuO) and H 3 Si(OCuO)Al(OH) 2 OSiH 3 (B 2 CuO) clusters. The interaction
