Chemistry of Pyrazolines : Part V - Syntheses and Mass Spectrometric Fragmentations of Some 4-Aryl-5-aroyl-2-pyrazolines

Sayed, G. H.,Kjoesen, H.

, p. 980 - 983 (2007/10/02)

Some new 4-aryl-5-aroyl-2-pyrazolines (1-5) have been synthesised by the reaction of diazomethane on chalkones and characterised by means of their physical properties (m.p., UV, IR, PMR and MS).Their electron impact induced mass spectrometric fragmentatio
