    • We previously reported on the synthesis of 3,5-diarylpyrazolines by addition of N-acetylhydrazines to chalcone derivatives catalysed by TBD guanidine. The same conditions applied to terminal enones 2 did not furnish the corresponding 3,4-substituted pyrazolines and led to a rapid decomposition of the unsaturated ketone. Enones 2 are indeed markedly prone to polymerisation under basic conditions or in the presence of strong nucleophiles such as monosubstituted hydrazines. See reference 10
