Pd-catalyzed reductive addition of organohalides, including aryl, alkenyl, and benzyl halides, to ynol ethers has been realized in the presence of 2-propanol, giving α,β- and β,β-disubstituted olefinic ethers in satisfactory yields with excellent regio- and stereoselectivity. It represents the first highly regio- and stereoselective hydroarylation, hydroalkenylation, and hydrobenzylation of ynol ethers.
在2-丙醇的存在下,已实现了钯催化的有机卤化物(包括芳基,烯基和苄基卤化物)的还原性加成反应,从而以令人满意的收率得到优异的α,β-和β,β-二取代烯烃醚区域和立体选择性。它代表了炔醇醚的第一个高度区域和立体选择性加氢芳基化,加氢烯基化和加氢苄基化。
