In the present paper [VO(acac)2] reacts with an equimolar amount of tridentate dibasic ONO donor hydrazone ligand derived from the condensation of benzoyl hydrazine with either 2hydroxyacetophenone (H2L 1) or its para-substituted derivatives (H2L 2) (general abbreviation H2L), in the presence of excess amount of salicylaldehyde (Hsal) in methanol under aerobic conditions producing the mixed-lig...

In this study, the Ni(II) Schiff base/SBA-15 catalyst was successfully synthesized and characterized by employing FT-IR, XRD, TGA, EDX, ICP-OES, TEM, SEM analysis. addition, BJH BET techniques were used to determine specific surface area, pore size, volume of catalyst, which 538 m2 g−1, 6 nm, 1.01 cm3 correspondingly. Under favorable conditions, we have designed a one-pot multicomponent reactio...

The use of transition-metal catalysis to form new C C bonds is an important tool in organic synthesis. Palladiumand nickel-catalyzed C C bond-forming reactions have been extensively explored and are well understood. The use of iron as the catalyst has gained much less attention, despite the innovative work of Kochi et al. in the 1970s. Recently, several groups have turned their attention toward...

Mercaptobenzoic acid-palladium(0) complexes show high catalytic activity for S-benzylation with benzylic alcohols via the (η(3)-benzyl)palladium(II) cation in water. Notably, these palladium(0) complexes could play an important role in formation of active (η(3)-benzyl)palladium(II) cation complexes followed by S-benzylation. Hammett studies on the rate constants of S-benzylation by various subs...

We present the linear response function of bond-orders (LRF-BO) based on a real space integration scheme for molecular systems. As in the case of the LRF of density, the LRF-BO is defined as the response of the bond order of the molecule for the virtual perturbation. Our calculations show that the LRF-BO enables us not only to detect inductive and resonating effects of conjugating systems, but ...

The quantitative structure activity relationship paradigm provides an excellent avenue for investigating ligand–receptor interactions in medicinal chemistry/toxicology. Lateral validation of models formulated using this approach allows for a cohesive understanding of the mechanistic underpinnings of a specific class of related molecules. The diverse biological activities of substituted phenols ...
