Synthesis of 4-hydroxy and 6-hydroxyindoles: a renaissance of the Bischler reaction
Chimica Techno Acta, 2022 In the present work we studied a modified Bischler-Möhlau reaction – synthesis of indoles from benzoin and aniline. Our proposed modification of this method differs from that described earlier in that the reaction is carried out at a lower temperature ...

(±) Methanodibenzodiazocine tethered [C-H]δ+ functional site: Study towards benzoin condensation and Baylis-Hillman reactions [PDF]
, 2015 New heterocyclic ring systems consisting of (±) methanodibenzodiazocine and imidazolium/ benzimidazolium salts were synthesized in very good yield. Subsequently, these halide salts were subjected to the anion exchange reaction with KPF6 to yield ...

Acta Crystallographica Section E Structure Reports Online, 2005 In the title compound, C15H15N3OS, the thiosemicarbazone moiety is planar, with a maximum deviation of 0.0369 (11) A, and has an E configuration. The planar phenyl rings make dihedral angles of 26.56 (9) and 81.20 (5)° with the plane of the thiosemicarbazone moiety. In the molecule, there are two intramolecular interactions of types N—H⋯O and N—H⋯N.

First direct evidence of N-heterocyclic carbene in BMIm acetate ionic liquid. An electrochemical and chemical study on the role of temperature [PDF]
, 2017 Cyclic voltammetry provides the first direct evidence of N-heterocyclic carbene (NHC) presence in neat 1-‐butyl-3-methylimidazolium acetate ionic liquid (BMImAcO) at 120°C. The NHC existence, proved by its oxidation current in cyclic voltammetry, was
