摘要: α,β-不饱和酮是重要的有机合成中间体,常用醇钠[1]或氢氧化钠[2]作催化剂由醛酮缩合合成,这时常由于强碱而发生副反应。Cava曾报道双对-甲氧苯基氧化碲(BMPTO)对醇醛缩合有一定催化作用[3]。本文以BMPTO为催化剂,通过Claisen-Schmidt反应合成了一系列α,β-不饱和酮和2,4-二烯酮。所得产物及其结构表征结果列于表1。

Abstract: 15α,β-unsaturated ketones and 12 2,4-alkadienones were prepared by the ClaisenSchmidt condensation reaction catalyzed by bis(p-methoxyphenyl)telluroxide(BMPTO). Allthe products are E-isomeric as confirmed by their m.p. and IR spectra determinations.

Key words: α,β-unsaturated ketone, alkadienone, bis(methoxyphenyl)telluroxide, Claisen-Schmidt condensation, synthesis
