Acid catalyzed nitrile thiolysis of 3-amino-acrylonitriles, toward the synthesis of 3,4-substituted-5-amino-isothiazoles

Application of an acid-catalyzed thioamidation of beta-amino-acrylonitriles to the corresponding beta-amino-thioacrylamides toward the synthesis of 3,4-substituted-5-amino-isothiazoles is described. The greatest yields were observed for examples with electron rich aromatic systems. This method uses inexpensive and easily handled reagents.

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.Reference of 288-16-4, you can also check out more blogs about288-16-4

The electronic states of isothiazole studied by VUV absorption spectroscopy and ab initio configuration interaction methods

The isothiazole VUV absorption spectrum over the range 5-12 eV shows (broad) intense bands centred near 5.17, 6.11, 7.37, 7.75, 9.18 and 10.43 eV. The lowest Rydberg states relating to the first ionisation energy are difficult to identify, but higher members are particularly numerous on the region from 8.4 to 9.6 eV. Electronic excitation energies for valence (singlet and triplet) and Rydberg-type states have been computed using ab initio multi-reference multi-root CI methods. These studies used a triple zeta + double polarisation basis set, augmented by diffuse (Rydberg) orbitals. The theoretical study shows the nature of the more intense Rydberg state types, and positions of the main valence and Rydberg bands. By study of the excitation energies to specific upper states, the vertical ionisation energies (IE) are confirmed as pi4- 1 < pi3- 1 < sigma18- 1 (LPN) < sigma17- 1 (LPS). Structures for the pi- and sigma-cations, and the (neutral) pipi*-triplet states have been obtained. Calculated energies for low-lying Rydberg states are close to those observed, and there is generally a good correlation between the theoretical intensities and the experimental envelope. The ground state atomic and molecular properties are in good agreement with experiment. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

Synthesis and properties of heterocyclic monoazo dyes derived from 3-cyano-4-trifluoromethyl-6-substituted-2(1H)-pyridinethiones

The synthesis and properties of new heterocyclic monoazo dyes derived from polyfunctionally substituted 3-amino-4-trifluoromethyl- thieno[2,3-b]pyridines as diazo components are reported. By appropriate selection of substituents in the coupling components, dyes varying in hue from yellow to blue can be obtained. The dyes were applied to polyester; their spectral, fastness properties and colour assessment are reported.

Survey of main group compounds (hbr) at the gaussian-4 level of theory: Adiabatic ionization energies and enthalpies of formation

Gas phase adiabatic ionization energies (AIEs) and standard state (298.15. K, 1. atm) enthalpies of formation DeltafH(g) were calculated at the Gaussian-4 (G4) level of theory for a suite of 319 and 398 main group compounds, respectively, containing the elements hydrogen through bromine. National Institute of Standards and Technology (NIST) evaluated AIEs were available for comparison with 44 compounds, yielding good agreement when the significant variability among the individual experimental reports was taken into consideration. AIEs were estimated at the G4 level of theory for a further 126 main group compounds having at least one experimental datapoint in the NIST database, but not a NIST evaluated AIE, as well as 149 main group compounds without any experimental data in the NIST database. Experimental DeltafH(g) were available for comparison with 144 compounds, yielding good agreement, particularly against compounds with evaluated DeltafH(g) DeltafH(g) were estimated at the G4 level of theory for a further 254 main group compounds without any experimental data. The datasets comprise a benchmark set of theoretical data against which to assess future experimental and theoretical results.

The electronic states of 1,2,5-thiadiazole studied by VUV absorption spectroscopy and ab initio configuration interaction methods

The 1,2,5-thiadiazole VUV absorption spectrum over the range 5-12 eV has been obtained for the first time. It shows broad bands centred near 5.0, 7.2, 7.7, 8.7, 9.6 and 10.6 eV; several of these show well resolved vibrational structure. A number of valence states and Rydberg states relating to the first and second ionisation energies have been identified. The doubling of some bands in the 4.7 eV region (previously reported) is confirmed; a 3s Rydberg state shows a similar phenomenon, which we also attribute to a non-planar upper state; a study of the (planar) equilibrium geometry of the corresponding triplet Rydberg state shows it is a saddle point. Electronic excitation energies for valence (singlet and triplet) and Rydberg-type states have been computed using ab initio multi-reference multi-root CI methods. These studies used a triple-zeta + double polarisation basis set, augmented by diffuse (Rydberg) orbitals. The theoretical study shows the nature of the more intense Rydberg state types, and positions of the main valence and Rydberg bands. There is generally a good correlation between the theoretical intensities and the experimental envelope. Reconsideration of the order of cationic states in the UV-photoelectron spectrum, crucial to the Rydberg state interpretation, has led to the sequence: 2B1 < 2B2 < 2A2 < 2A1. Study of the excitation energies to specific upper states, also supports this order. The value of IE1 is refined to 10.111 eV. Equilibrium structures show the pi- and sigma-cations are planar, in contrast to the lowest triplet state. Do you like my blog? If you like, you can also browse other articles about this kind.
