Bimanes (1,5-Diazabicyclo(3.3.0)Octadiendiones). Laser Activity in syn-Bimanes.

摘要

The conversion of 3-methyl-4-benzyl-4-chloro-2-pyrazolin-5-one 10b was catalyzed by a mixture of potassium fluoride and alumina to give syn-(methyl,benzyl)bimane 6 (62%) without detectable formation of the anti isomer A6(a 1:1 mixture (87%) of the isomers 6 and A6 was obtained when the catalyst was potassium carbonate). Keywords: Syn-Bimanes, Laser activity, Synthesis of syn-bimanes, Spectroscopic and laser action properties of syn-bimanes, Isomers. (JG)
