Le 1,1’-dibenzyl-5,5’-diisopropyl-3,3’-bipyrazole a été synthétisé de façon régiosélective par la dibenzylation d’un nouveau dérivé du 3,3’-bipyrazole. Le produit obtenu a été clairement caractérisé par les données spectrales (IR, RMN 1H, 13C, masse) analyse élémentaire et par rayons X.A new 3,3’-bipyrazole derivative was prepared and regioselectively dibenzylated to afford a target product 1,1’-dibenzyl-5,5’-diisopropyl-3,3’-bipyrazole which clearly established from spectroscopic data (IR, 1H and 13C NMR, mass spectrometry and elemental analysis) and X-ray crystallography
