Palladium-catalyzed regio- and stereoselective selenoacylation of allenes with selenol esters proceeded to produce functionalized allyl selenides with the acyl moiety at the inner carbon and the SePh group at the terminal carbon in high yields. A mechanism accounting for the observed regio- and stereoselectivities is proposed based on the results of DFT calculations.
用亚硒酸酯对钯进行的钯催化的区域和立体选择性硒酰基化反应以高收率生产了官能化的烯丙基硒化物,其内部碳原子为酰基部分,而在末端碳原子为SePh基团。基于DFT计算的结果,提出了一种解释观察到的区域选择性和立体选择性的机制。
