Morin, Frederick G. published the artcileCarbon-13 magnetic resonance of hydroaromatics. II. Conformation of Tetralin and tetrahydroanthracene and their methyl derivatives, Related Products of catalysis-chemistry, the publication is Journal of the American Chemical Society (1983), 105(12), 3992-8, database is CAplus.
13C NMR chem. shifts are determined for 36 methylated tetralins and tetrahydroanthracenes. A least-squares regression anal. of the ring C atoms in compounds of unequivocal conformation is used to estimate Me substituent parameters for the 2 distinct aliphatic positions, and the results are used to estimate the position of equilibrium of conformationally mobile compounds 1-Methyltetralin exists in essentially equally populated conformers at room temperature; the 2-Me derivative is dominated by the conformation with an equatorial Me group. Substituent parameters are compared with those previously determined for methylated cyclohexanes. A similar anal. of the Me chem. shifts was unsuccessful due, in part, to the highly flexible nature of the saturated ring.
Journal of the American Chemical Society published new progress about 1949-41-3. 1949-41-3 belongs to catalysis-chemistry, auxiliary class Carboxylic acid,Benzene, name is 2-Methyl-4-phenylbutanoic acid, and the molecular formula is C11H14O2, Related Products of catalysis-chemistry.
