含烯丙基硒醚结构单元的α,β-不饱和酮的合成和表征

Synthesis and Characterization of α,β-Unsaturated Ketones Containing Allylic Selenides

通过炔丙基硒醚与一氯一氢二茂锆的锆氢化反应及其进一步与过量醛的反应,以中等到良好的产率得到了含烯丙基硒醚结构单元的α,β-不饱和酮.化合物经1H NMR,IR,MS和元素分析表征.光谱分析数据表明合成的α,β-不饱和酮中的双键构型为E型.

α, β-Unsaturated ketones containing allylic selenides was synthesized in moderate to good yields by hydrozirconation of proparyl selenides and its further reaction with aldehydes. All the products were characterized by ^1H NMR, IR, MS and elemental analysis. The results show that the configurations of the products are in E-fashion.
