Herein, we report an efficient method for synthesis of novel selenocyanates amino pyrazole, uracil, and isoxazole derivatives using in situ triselenium dicyanide from the combination malononitrile selenium dioxide DMSO medium. Using same but changing stoichiometry reagents sequence addition temperature, symmetrical selenoethers pyrazoles uracils were prepared good yields. Furthermore, utilized ...

ABSTRACT. The synthesized Zeolite A/ZnCl2 nanoparticles via the hydrothermal route were characterized using FTIR, XRD, and SEM/EDAX techniques. catalyst was used for eco-friendly synthesis of 4,5-dihydro-pyrazole-1-carbothioamide derivatives. Under solvent-free conditions, a multi-component reaction between hydrazine, isothiocyanate, chalcone done with prepared nano-catalyst as an inexpensive, ...
