A Pd-catalyzed highly regioselective 1,2-difunctionalization of vinylarenes is disclosed in which multisubstituted olefins are efficiently and conveniently constructed under ambient temperature with good compatibility and a broad substrate scope. Notably, a quarternary carbon center could be readily built up from 1,1-disubstituted styrenes, which are big challenges in the previous methods.
公开了Pd催化的乙烯基芳烃的高度区域选择性的1,2-二官能化,其中在环境温度下以良好的相容性和广泛的底物范围有效且方便地构建了多取代的烯烃。值得注意的是,可以很容易地由1,1-二取代的苯乙烯建立一个四级碳中心,这在以前的方法中是很大的挑战。
