超声波辐射α、β—不饱和酮的合成

Synthesis of α,β-unsaturated Ketones by Means of Supersonic Radiation

报道在超声波作用下,利用芳醛和芳基乙酮的10%氢氧化钠体系中的缩合反应来合成α、β——不饱和酮的实验,探讨了缩合反应的条件,合成了七种α、β——不饱和酮,并由红外光谱表征其结构.

Seven compounds of α、β-unsaturated ketones have been synthesized using upersonic wave radiation in the presence of 10% NaOH and phase thansfer catalyst.Com- pared with the classical methods,this technique has many advantages,such as good yields, short reaction time,easy preparation and mild reaction conditions.
