Article abstract of DOI:10.1021/jo00288a032

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
