Functionalized isoxazole and isothiazole ligands: design, synthesis, palladium complexes, homogeneous and heterogeneous catalysis in aqueous media

Homogenous and heterogeneous palladium catalysts with functionalized izoxazole and isothiazole ligands were developed for the cross-coupling reactions. The catalysts possessed high activity and were suitable for the repeated use. Compared with commonly used organic solutions, application of water and its mixtures with methanol as a reaction medium significantly intensifies catalysis with no side being formed. The obtained results are promising for the development of effective and ecologically friendly technologies of synthesis of important compounds such as polyfunctional biaryls, arylated olefins, acetylenes and their heterocyclic analogs.

Reference of 35285-69-9, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 35285-69-9.

SYNTHESIS AND RECEPTOR-BINDING OF 5-AMINO[H-3](2)METHYL-3-ISOTHIAZOLOL ([H-3]THIOMUSCIMOL), A SPECIFIC GABA(A) AGONIST PHOTOAFFINITY LABEL

The synthesis of tritium labelled thiomuscimol (5-amino[H-3](2)methyl-3-isothiazolol) (7c), a specific and high-affinity agonist photoaffinity label for GABA(A) receptors, is described.

An isoxazole-based polymeric co-ordination network incorporating a helical Ag(I)-S structural motif

An isoxazole-based ligand 2 bearing a thioether side arm in the 5-position of the heterocycle forms a polymeric coordination network with Ag(ClO4) (space group Aba2), in which the ligand is coordinated to three different silver ions via the ring N and the bridging thioether-S. The resulting layer structure consists of infinite Ag(I)-S helices linked by the isoxazole moieties, with the latter being stacked above each other. A related complex 2 . AuCl (space group C2/c) features linear S-Au-Cl units associated by weak d(10)-d(10) interactions, while the isoxazole nucleus remains uncoordinated. The solid state structures are compared to those of related isothiazole complexes. (C) 1999 Elsevier Science Ltd. All rights reserved.

Theoretical Calculation of Thermodynamic and Kinetic Quantities for 1,3 Dipolar Cycloaddition Reactions Between Nitrile Sulfides R-CNS (R = H, CH3, Ph and Ph(CH3)(3)) with 7-10 Membered Simple Cycloalkynes

The 1,3-dipolar cycloaddition reactions also known as the Huisgen cycloaddition are one of the most widely used and versatile preparative methods in hetro-cyclic chemistry. In this study, the reactivity and strain energy effect of the simple cycloalkynes with substituted Nitrile sulfides R-CNS (R = H, CH3, Ph and Ph(CH3)(3)) will be discussed in light of computational studies using DFT methods (B3LYP/6-31G*). The investigation of the structured properties, theoretical thermodynamic and kinetic data of the reactions in 298 K will be presented. The results show increase in the Delta G* by increasing the ring size and decreasing the strain energy of cycloalkynes. Also, the rate constants and the free energy changes in reactions increase as the size of the ring decreases. The relationships of the deviation of the internal bond angle (DIBA, in degrees), pi-strain (S pi) (in kcal mol(-1)), the bond angle of Csp(3)-C C (theta degrees) and Delta G(#)(kcal mol(-1)) for the series of cycloalkynes I-1 to I-4 have investigated.
