Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 2-Furoic hydrazide, is researched, Molecular C5H6N2O2, CAS is 3326-71-4, about Kinetic and mechanistic analysis of oxidation of 2-furoic hydrazide by hexachloroirradate(IV) in a wide pH range.Product Details of 3326-71-4.

Oxidation of 2-furoic hydrazide (FH) by hexachloroiridate(IV) ([IrCl6]2-) was studied kinetically in a wide pH range in aqueous solution of 1.0 M ionic strength. The oxidation reaction followed well-defined second-order kinetics: – d[IrCl62-]/dt = k'[FH]tot[IrCl62-], where [FH]tot denotes the total concentration of FH and k’ stands for the observed second-order rate constants The established k’-pH profile displays that k’ increases drastically with pH and a plateau region exists between pH 4 and 6. A stoichiometric ratio of Δ[FH]tot/Δ[IrCl62-] = 1/4 was revealed by spectrophotometric titrations 1H NMR spectroscopic studies indicated that FH was cleanly oxidized to 2-furoic acid. The kinetic data suggest a reaction mechanism in which all the three protolysis species of FH react with [IrCl6]2- in parallel, forming the rate-determining steps. Two stabilized hydrazyl radicals are generated in the rate-determining steps, in which a single electron is transferred to [IrCl6]2-. The two hydrazyl radicals react rapidly in consecutive steps requiring 3 mol of Ir(IV) to form 2-furoic acid as the final product. Rate constants of the rate-determining steps were deduced through a simulation of the rate expression to the k’-pH dependency data. Values of these rate constants demonstrate that the three protolysis species of FH have a huge reactivity span, changing by about 109 times toward reduction in [IrCl6]2- and that FH can be readily oxidized in neutral and basic media. Rapid scan spectra and the measured activation parameters suggest that an outer-sphere electron transfer is probably taking place in each of the rate-determining steps. This is the first kinetic study on the oxidation reactions of FH and provides concurrently the protolysis constants of FH (pKa1 = 3.04 ± 0.08 and pKa2 = 11.6 ± 0.1) at 25.0 °C and 1.0 M ionic strength.

An ultrasound-assisted method facilitated by lemon juice has been developed to synthesize 2-amino-1,3,4-thiadiazole derivatives I (Ar = Ph, 2-methoxy-5-nitrophenyl, pyridin-3-yl, etc.) that could act as potential anticancer agents. Accordingly, a convenient method has been developed for the rapid synthesis of this class of compounds I under a mild and non-hazardous reaction condition in good yields. The methodol. involved the reaction of various acid hydrazides ArC(O)NHNH2 with TMSNCS in the presence of lemon juice in PEG-400 at room temperature (25-30°C) under ultrasound irradiation These compounds I were assessed for their cytotoxic properties against two different metastatic breast cancer cell lines e.g., MDAMB-231 and MCF-7 and subsequently against SIRT1. The 2-amino 1,3,4-thiadiazole derivatives I (Ar = 4-methoxyphenyl, 3-methoxyphenyl, 2,3-dimethoxyphenyl, 2-methoxy-5-nitrophenyl) showed promising growth inhibition of MDAMB- 231 and MCF-7 cell lines and SIRT1 inhibition in vitro. Indeed, I (Ar = 3-methoxyphenyl) was found to be a potent inhibitor of SIRT1.

We’ll tell you more about this compound (cas:3326-71-4).

Furo-(phenyldimethine)carbohydrazone (H2L) was prepared via the condensation reaction of 2-furoic acid hydrazide with terephthaldehyde by (2:1) molar ratio. Octahedral and square planar complexes were synthesized from the reaction of (H2L) ligand with chloride salts of Co(II), Ni(II), Cu(II), Ru(III) and Pd(II) ions. All the chelates were structurally characterized by various anal. and spectral techniques. The stoichiometry of chelates was found to be 1:1, 1:2 and 1:3 (L:M) molar ratios to form sandwich, binuclear and trinuclear complexes, resp. All complexes were found to be non-electrolytic in nature on the basis of molar conductance values. The IR data showed that the ligand served as tetradentate in a neutral keto form. The ligand coordinated with all metal ions via oxygen atoms of carbonyl group and furan ring. The thermal properties of the ligand and its chelates were investigated utilizing thermogravimetry and reflected that Ru(III) complex has lower thermal stability than other complexes. X-ray diffraction spectra established nano-size for Ni(II) and Ru(III) complexes. The ESR result revealed axial symmetry with hyperfine structure for Cu(II) complex indicative of (2B1g) as a ground state. Some quantum parameters were reported in order to compare the reactivity of the compounds The biol. data indicated that all complexes have cytotoxic and antioxidant activity rather than the native ligand. Among all complexes, Ru(III) complex had excellent cytotoxic and antioxidant activity. This was due to its chem. structure and its nano-size.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 37443-42-8, is researched, Molecular C6H10O3, about Divergent Reactivity during the Trapping of Benzynes by Glycidol Analogs: Ring Cleavage via Pinacol-Like Rearrangements vs Oxirane Fragmentations, the main research direction is benzyne trapping glycidol analog hydro cyclic ether reactivity.SDS of cas: 37443-42-8.

Hydroxy-containing cyclic ethers react with thermally generated benzynes to produce aryl ethers. Diverse reactivity was observed Cleavage of the cyclic ether was involved in most of the pathways. The transformations are rationalized via initial formation of oxonium ion-containing 1,3-zwitterions arising from preferential nucleophilic attack on the benzyne by the ether oxygen. Pinacol-like rearrangements, including ring expansion, to yield aldehydes or ketones and oxirane fragmentations to generate aryl enol ethers were main competing events.
