摘要

Abstract The synthesis and spectral characteristics of a bis-spiro compound: 2, 6-bis (4- phenyl-3-δ 1-pyrazolinyl) cyclo-hexanone are reported. Unlike literature reports, this particular δ 1-pyrazoline does not readily rearrange to the 2 isomer on heating. Pyrolysis gives 2, 6-bis (α-methylbenzylidene) cyclohexanone. A monopyrazolinylket-one was also isolated which is most likely an intermediate in the bis-denitrogenation. A mechanism for ...
