## Abstract Reaction kinetics for the condensation of 1,3‐diketones **1a–o** with selected arylhydrazines (aryl = Ph, 4‐NO~2~Ph, 4‐CH~3~OPh, and 2,4‐diNO~2~Ph) was studied using ^19^F NMR spectroscopy. Product regioselectivity is modulated by reactant ratios, substituents, and acidity. Reaction rat
