CH?S hydrogen bonds as the organising force in 2,3-thienyl- and phenyl- or 2,3-dithienyl-substituted propenoic acid aggregates studied by the combination of FT-IR spectroscopy and computations

Various propenoic acid stereoisomers 2,3-disubstituted with thienyl and/or phenyl groups were synthesised and their aggregation behaviour was studied both in solution and in the solid state by experimental (mid-range FT-IR spectroscopy) and computational

THE MASS SPECTRA OF SOME (E)- AND (Z)-α-(PHENYL)-β-(2-THIENYL)ACRYLAMIDES

Mass spectra of some (E)- and (Z)-α-(4-X-phenyl)-β-(2-thienyl) acrylamides at 70 eV are reported.The stereoisomeric compounds do not show significant differences.The mass spectra show a four centre reaction scheme with NH2 migration to the β-carbon atom and subsequent fission of Cα-Cβ bond.

Structural Effects of the Acidity of E-α-Phenyl-β-arylacrilic Acids

The dissociation equilibrium constants of some E-α-phenyl-β-arylacrilic acids (Ar=2-pyridyl, 3-pyridyl, 4-pyridyl, 1-naphthyl, 2-naphthyl, anthracen-9-yl) have been measured in 80percent aqeous 2-methoxyethanol at 25 deg C., The pKa values of these acids, together with those of p-substituted phenyl, 2-furyl, 2-thienyl and selenophen-2-yl derivitives, have been rationalized by an equation involving separate contributions of polar, conjugative and steric effects of heterocycles.The pKa values of some E-α-phenyl-β-alkylacrilic acids (alk=methyl; ethyl; n-propyl; i-propyl; n-butyl; i-butyl) are also reported.
