In the present study, a new hydrazone ligand (2-((2-phthalazin-1-yl)hydrazono)methyl)phenol) prepared by condensation of hydralazine (1-Hydralazinophthalazine) with salicylaldehyde (SAH). The synthesized SAH-hydrazone and its metal complexes have been characterized by elemental analyses, IR, H-1 NMR, solid reflectance, magnetic moment, molar conductance, mass spectra. UV-vis and thermal analysis (TGA). The analytical data of the complexes show the formation of 1:1 [M:L] ratio, where M represents Ni(II), Co(II) and Cu(II) ions, while L represents the deprotonated hydrazone ligand. IR spectra show that SAH is coordinated to the metal ions in a tridentate manner through phthalazine-N, azomethine-N and phenolic-oxygen groups. The ligand and their metal chelates have been screened for their antimicrobial activities using the disc diffusion method against the selected bacteria and fungi. Proton-ligand association constants of (SAH) and the stepwise stability constants of its metal complexes are determined potentiometrically in 0.1 M NaNO3 at different temperatures and the corresponding thermodynamic parameters were derived and discussed. The order of -Delta G degrees and -Delta H degrees were found to obey Mn2+ < Co2+ < Ni2+ < Cu2+, in accordance with the Irving-Williams order. The complexes were stabilized by enthalpy changes and the results suggest that the complexation is an enthalpy-driven process. The concentration distribution diagrams of the complexes are evaluated.

In a document, author is Zhou, Jiadi, introduce the new discover.

An efficient silver-catalyzed d-regioselective C(sp(3))-H heteroarylation of free alcohols has been developed. Various alcohols reacted with quinolines, isoquinoline, pyridines, pyrimidine, phthalazine, 4-hydroxyquinazoline, acridine, quinoxaline and pyrazine to give the corresponding C(sp(2))-H alkylation products in 31-89% yields. Notably, all types (1 degrees, 2 degrees, and 3 degrees) of d-C(sp(3))-H bonds in the alcohols could be regioselectively activated. This protocol provides a platform to access divergent functionalizations of alcohols and heteroaryls by forming the challenging d-selective C(sp(3))-C(sp(2)) bond.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 83-53-4. Application In Synthesis of 1,4-Dibromonaphthalene.

A highly active and stable ionic liquid based novel solid Bronsted acid catalyst (C@TiO2-SO3H-ILs) was prepared by coating a long chain ionic liquid onto sulfonated carbon@titania composites. The ionic liquid coating resulted in efficient stability and activity of C@TiO2-SO3H-ILs under aqueous conditions by creating a hydrophobic environment on the catalyst surface. The catalytic activity of the newly designed catalyst was tested in the one-pot multicomponent synthesis of indeno[1,2-b]indole-9,10-diones and 1H-pyrazolo[1,2-b]phthalazine-5,10-diones in aqueous media. The structure of the most active catalyst, C@TiO2-SO3H-IL1, before and after the coating with the ionic liquid was investigated by FTIR, TGA, XRD, CHNS, EDX, SEM and HRTEM. The catalyst allows easy recovery and excellent reusability for up to five catalytic runs without considerable loss of activity.

Recently, we described the first inverse electron demand Diels-Alder reaction of 1,2-diazene catalyzed by a bidentate Lewis acid. Herein we investigate 1,2-phenylenediboronic esters as potential catalysts for this transformation offering higher stability and easier handling than the currently used boranthracene derivatives. Different 1,2-phenylenediboronic esters were prepared and their ability to form bidentate coordination complexes with phthalazine was analyzed. Although a 1:1 complex was observed, X-ray analysis revealed binding only in a monodentate fashion.
