An efficient synthesis of new N-pyrazolyl benzodiazaphosphole-2-sulfides conjugates
Written by sctunisie no commentsA series of novel N-pyrazolyl benzodiazaphosphole-2-sulfides (4a-h) were prepared via cyclocondensation reactions between different 5-(2-aminophenylamino)-3-pyrazole derivatives (3a-h) and the Lawesson’s reagent. Structural elucidations of all compounds were established by mean of 1D-NMR spectroscopy: 1H, 13C, 31P, 2D-NMR techniques and HRMS analysis.
