In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. In homogeneous catalysis, catalysts are in the same phase as the reactants. 83-56-7, Name is Naphthalene-1,5-diol, molecular formurla is C10H8O2. In a document, author is REDDY, DB, introducing its new discovery. SDS of cas: 83-56-7.
TETRAHYDRO-1,4-THIAZINE-1,1-DIOXIDES .4. SYNTHESIS AND CONFORMATIONAL-ANALYSIS OF SOME 2,3,5-TRISUBSTITUTED TETRAHYDRO-1,4-THIAZINE-1,1-DIOXIDES
A series of new 2-aroyl-3, 5-diaryltetrahydro-1, 4- thiazine-1, 1-dioxides (2) has been synthesized either from phenacylsulfonylacetic acids (1) or phenacylstyryl sulfones (3), which in turn are obtained from the substituted acetophenones or styrenes, respectively. Another series of alkoxycarbonyl-3-aryl-5(4-methyl-phenyl)tetrahydro-l, 4-thiazine-1, 1-dioxides (5) has been prepared from Z (or E)-alkyl 4-methylstyrylsulfonyl acetates (4). The desired 4 has been obtained from the corresponding acetylenes or 4-methylstyrene. The structures of 2 and 5 and their preferred chair conformations have been deduced by the analysis of high resolution NMR data supported by correlation spectroscopy.
Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. A catalyst, therefore, does not appear in the overall stoichiometry of the reaction it catalyzes.I hope my blog about 83-56-7 is helpful to your research. SDS of cas: 83-56-7.
