1-Acetyl-, 1-propionyl- and 1-phenyl-3,5-diaryl-2-pyrazolines have been synthesized by the reaction of the appropriate α,β-unsaturated ketones with hydrazine or phenylhydrazine in hot acetic acid or propionic acid. Structures of all new 2-pyrazolines 16-40 have been elucidated by microanalyses, 1H and 13C nmr spectroscopies.
通过适当的α,β-不饱和酮与肼或苯肼在热乙酸或丙酸中的反应,已经合成了1-乙酰基,1-丙酰基-和1-苯基-3,5-二芳基-2-吡唑啉。所有新的2-吡唑啉16-40的结构已通过微量分析,1 H和13 C nmr光谱学得以阐明。
