Addition of 4-Phenyltriazolinedione to Carbonyl Compounds: The Formation of α-Urazolylcarbonyl Compounds

N-Phenyltriazolinedione (PTAD) adds to a variety of carbonyl compounds to form α-urazolylcarbonyl compounds.With highly enolized carbonyl systems, this type of substitution reaction can occur rapidly even in the absence of a catalyst.However, with simple

Mechanistic Studies of the Reaction of 4-Substituted 1,2,4-Triazoline-3,5-diones with β-Dicarbonyl Compounds

4-Substituted 1,2,4-triazoline-3,5-diones were found to add to the α position of β-diketones and β-diketo esters, yielding both 1:1 and 2:1 adducts.The 1:1 adducts showed a dramatic stabilization of the enolic tautomer when compared to the original β-dica
