Add to ORKGNuclear Magnetic Resonance (NMR) has been used to study the keto-enol equilibrium in a number of trifluoromethyl S-diketones as well as the dihydropyrazoles obtained when these S- diketones are reacted with thiosemicarbazide. The technique of Aromatic Solvent-Induced Shifts (ASIS) has been used to study the geometry of the collision complex and the strength of the association between solute and solvent. From the data presented, the stereochemistry of these pyrazoles has been determined and a reaction mechanism for their formation has been proposed
