SYNTHESIS AND THERMAL-DECOMPOSITION OF 3-AROYL-4-ARYL-2-PYRAZOLINES

3-Aroyl-4-aryl-2-pyrazolines (21-40) have been synthesized by the reaction of alpha,beta-unsaturated ketones (1-20) with diazomethane. These 2-pyrazolines gave beta-methyl-alpha,beta-unsaturated ketones (41-46) on thermal denitrogenation.
