Synthesis and rearrangement of 5-isothiocyanatopyrazolines

Autor: Rosario Brievaa, Vicente Gotor, Felix H. Cano, Ma de la Concepción Foces-Foces

Publikováno v: Tetrahedron. 45:1783-1792

1-(3-Iminoprop-l-enyl)-5-isothiocyanato-2-pyrazolines have been synthesized by reaction of hydrazine derivatives with carbon disulfide. These pyrazoline derivatives are precursors of pyrimidinylpyrazoles.

The structure of indazolinone and derivatives in the solid state and in solution: an X-ray and nuclear magnetic resonance study

Autor: Robert Faure, Ma de la Concepción Foces-Foces, Felix H. Cano, Albert Rousseau, Paloma Ballesteros, Rosa M. Claramunt, José Elguero

Publikováno v: J. Chem. Soc., Perkin Trans. 2. :1677-1681

The structure of indazolinone and some of its derivatives was obtained by the combined use of crystallography, 13C CP/MAS, and 15N n.m.r. It was concluded that indazolinone exists as such in the solid state but only as a minor tautomer (15%) in DMSO
