Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, causing turnover rates to depend strongly on interfacial structure and composition, 3034-86-4, Name is Methyl 4-ethynylbenzoate, SMILES is O=C(OC)C1=CC=C(C#C)C=C1, in an article , author is Assy, MG, once mentioned of 3034-86-4, Safety of Methyl 4-ethynylbenzoate.

Synthesis of some new pyrimidines, thienopyrimidines and thiopyranopyrimidines

Isothiocyanate 1 reacted with enaminone 2 to give thioamide 3 that cyclized by sodium hydroxide to pyrimidine 4 but cyclized by bromine to give isothiazole 5, pyrimidine 4 was transformed into thiopyranopyrimidines 7, 9 or 11 upon respective reaction with benzaldehyde, maleic acid, or maleic anhydride. Aminative cyclization of 4 yielded isothiazolopyrimidine 13. Reaction of 4 and ethyl bromoacetate or phenacyl bromides afforded thienopyrimidines 15a-b respectively. Oxidation of 4 yielded oxopyrimidine 16.

Synthesis and antiviral activity of a new series of 4-isothiazolecarbonitriles

A series of 4-isothiazolecarbonitriles was synthesized and screened for in vitro antiviral activity. The effect of various substituents on the phenyl ring, as well as the substitution of the phenyl for other aromatic and heteroaromatic rings, was examined to establish the requirements for optimum activity. The most active member of the series, 3-methylthio-5-phenyl-4-isothiazolecarbonitrile, exhibited a high level of activity against enteroviruses polio 1 and ECHO 9. Preliminary studies on its mechanism of action indicated that this compound had an effect on an early event in the replication of poliovirus type 1. (C) 1998 Published by Elsevier Science Ltd.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 3034-86-4, Name is Methyl 4-ethynylbenzoate, formurla is C10H8O2. In a document, author is Incerti, Matteo, introducing its new discovery. Computed Properties of C10H8O2.

Investigation of the Reaction between 3-Benzisothiazolones, an Isoindole Isoster and Activated Acetylenes: Synthesis of Heterocyclic Backbones for Building Bioactive Molecules

Investigation of the reaction between benzo[d]isothiazol-3-one, 2-aminobenzo[d]isothiazol-3-one, its isoster 2-aminoisoindolin-1-one, and activated acetylenes, in the presence of triphenylphosphine, led us to synthesize novel heterocyclic compounds that could be attractive for the building of biologically active molecules. A one-pot PPh3-promoted tandem reaction, with acetylene dicarboxylates and dibenzoylacetylene, afforded new tricyclic pyrazolo-fused benzisothiazoles. The PPh3-promoted reaction between benzisothiazolones and methyl propiolate afforded 1,4-benzothiazepine-5-one derivatives, via an isothiazole ring expansion. These studies are providing additional insights in benzisothiazolone chemistry and describe simple and original synthetic accesses to novel derivatives.

High-resolution infrared analysis of seven fundamental bands of gaseous isothiazole between 750 and 1500 cm(-1)

The gas phase IR spectrum of isothiazole, C3H3NS, between 550 and 1700 cm(-1) was recorded with a resolution of ca. 0.003 cm (-1). The rotational structure of seven fundamental bands in the region 750-1500 cm-1 has been assigned and analysed by the Watson Hamiltonian model. A number of local resonances in the bands have been identified and explained qualitatively in terms of Coriolis interactions. For each band upper state spectroscopic constants, including band center, rotational constants, and quartic centrifugal distortion constants are given. From observed crossings due to resonances we locate the weak bands v(9)(A’) and v(13)(A’) at 1041.9(2) and 642.0(3) cm(-1) respectively. The anharmonic frequencies have been determined using a cc-pVTZ basis set, at the MP2 and B3LYP levels; the two theoretical methods give very similar results for rotational constants, anharmonic band center frequencies and distortion constants, and many of these are in good agreement with experiment.

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 3034-86-4. Product Details of 3034-86-4.
