A reaction route accounting for the formation of levulinic acid from 5hydroxymethylfuran-2-carbaldehyde was deduced on the basis of the mechanism previously offered by Horvat, to match the steps with more details. A newly deduced reaction route was proposed between two intermediate products within this mechanism, and the probabilities of the two mechanisms were compared by Gaussian 03 software....

The mol-ecule of the title compound, C(14)H(9)NO(2)S, is nearly planar, the maximum atomic deviation being 0.081 (2) Å. An intra-molecular O-H⋯N bond generates an S(6) ring motif. In the crystal, inversion-related mol-ecules linked by a pair of weak C-H⋯O hydrogen bonds form a supra-molecular dimer. π-π stacking is observed between the thia-zole and benzene rings of adjacent mol-ecules, the cen...

The present article includes the generation of aromatic Schiff base tethered organosilatranes via two step synthetic pathways starting from anthracene-10-carbaldehyde and 1H-indole-3-carbaldehyde. synthesis was achieved by employing condensation reaction followed transesterification methodology. prepared containing schiff based ligands were structurally authenticated using spectroscopic techniq...
