The synthesis and spectral characteristics of a bis-spiro compound: 2,6-bis(4-phenyl-3-Δ1-pyrazolinyl)cyclohexanone are reported.Unlike literature reports, this particular Δ1-pyrazoline does not readily rearrange to the δ2 isomer on heating.Pyrolysis gives 2,6-bis(α-methylbenzylidene)cyclohexanone.A monopyrazolinylketone was also isolated which is most likely an intermediate in the bis-denitrogenation.A mechanism for the denitrogenation-rearrangement is proposed.
