A palladium‐catalyzed bisallylation of vinylethylene carbonates with β‐ketophosphonates to access to (Z)‐trisubstituted dihomoallylic phosphonates bearing a quaternary carbon center with good regio‐ and stereoselectivity is reported. This operationally simple protocol exhibits excellent functional group tolerance to deliver valuable dihomoallylic phosphonates.

钯催化乙烯基乙炔碳酸酯与β-酮基膦酸酯的双烯丙基化反应，与季碳中心立体选择性合成（Z）-二烯丙基膦酸酯

据报道，碳酸亚乙烯酯与β-酮膦酸酯进行钯催化的双烯丙基化反应，可制得具有良好区域和立体选择性的带有季碳中心的（Z）-三取代二高芳基膦酸酯。该操作简单的协议显示出出色的官能团耐受性，可提供有价值的二缩水烷基膦酸酯。
