Rhodium-catalyzed carbonylation of allyl phosphates under CO (20 atm) at 50°C proceeds very efficiently in the presence of amines, alcohols, and water to give the corresponding β,γ-unsaturated amides, esters, and acids, respectively. These carbonylations occur with high regioselectivity at the less substituted carbon of allyl unit to give linear β,γ-unsaturated acid derivatives.
在胺,醇和水的存在下,在50°C的CO(20 atm)下铑的烯丙基磷酸酯的羰基催化羰基化反应非常有效,分别得到相应的β,γ-不饱和酰胺,酯和酸。这些羰基化在烯丙基单元的较少取代的碳上以较高的区域选择性发生,从而得到线性的β,γ-不饱和酸衍生物。
