developed, which generates a range of previously underexplored α-substituted β-ketophosphonates in 55~70% yields. Furthermore, a convenient one-pot procedure by direct conversion of styrenes to α, β-unsaturated ketones is also developed based on the new catalytic reactions, thus offering a protocol to access two classes of valuable products from simple starting materials.
开发了第一个在露天条件下铁催化苯乙烯衍生物与 H-膦酸二烷基酯的氧代磷酸化反应,生成了一系列先前未充分开发的 α-取代的β-酮膦酸酯,产率 55~70%。此外,基于新的催化反应,还开发了一种方便的一锅法,将苯乙烯直接转化为α,β-不饱和酮,从而提供了一种从简单的起始原料获得两类有价值的产品的方案。
