1‐Arylvinyl formates as a kind of new CO surrogate have been explored for the first time. Most of the known CO precursors usually produce undesired residuals, which have to be removed. In this strategy, after CO release, the in situ generated acetophenones from 1‐arylvinyl formates can be successfully applied as a good ketone source in the synthesis of chalcones with benzaldehydes via a palladium‐catalyzed
首次探索了1-芳基乙烯基甲酸酯作为一种新的CO替代物。大多数已知的CO前体通常会产生不希望有的残留物,必须将其除去。在该策略中,释放出CO后,由1-芳基乙烯基甲酸酯原位生成的苯乙酮可通过钯催化的还原羰基化反应成功地用作苯甲醛与查耳酮合成的良好酮源。在温和条件下,以令人满意的产率获得了各种查耳酮,并具有良好的底物相容性。
