前文我们报道了溴化对-苯基苯甲酰甲基二丁基碲、溴化对-溴苯甲酰甲基二丁基碲和溴化间-硝基苯甲酰甲基二丁基碲等碲盐与醛、酮缩合成α,β-不饱和酮的反应。为了进一步研究碲盐反应性能,扩大它在有机合成中应用范围,我们在前期工作基础上,由碲盐和(E)-α,β-不饱和醛合成了2,4-共轭不饱和酮、酯、腈,这是一种未见文献报道的新合成方 We have reported previously that p-bromophenyl p-bromobenzyl dibutyl tellurium bromide, p-bromophenacyl dibutyl tellurium bromide and m-nitrophenacyl dibutyl telluride bromide Such tellurium salts and aldehydes, ketones condensation into α, β-unsaturated ketone reaction. In order to further study the reaction performance of tellurium salt and expand its application scope in organic synthesis, we synthesized 2,4-conjugated unsaturated ketone from tellurium salt and (E) -α, β-unsaturated aldehyde based on the previous work , Ester, nitrile, which is a new synthesis of the literature has not been reported
