A mild and novel palladium(II)-catalyzed domino Heck/Suzuki alpha,beta-diarylation-reduction of a dimethylaminoethyl substituted chelating vinyl ether was developed by using electron-rich arylboronic acids in combination with p-benzoquinone. Based on the preparative results, a catalytic cycle is proposed. Further, highly regioselective palladium(II)-catalyzed alpha- or beta-monoarylation of the chelating
通过使用富含电子的芳基硼酸与对苯醌组合,开发了轻度新颖的钯(II)催化多米诺骨牌Heck / Suzukiα,β-二芳基还原反应的二甲基氨基乙基取代的螯合乙烯基醚。基于制备结果,提出了催化循环。此外,使用二齿配体或通过采用少配体条件,实现了高度区域选择性的钯(II)催化的螯合乙烯基醚的α-或β-单芳基化。
