Palladium-catalyzed domino reactions of (E)-1,2-dibromoethenes with hindered Grignard reagents based on carbopalladation, palladium-catalyzed cross-coupling, and C-H activation are described. These domino reactions could be influenced by the ligand, reaction temperature, nucleophilicity of Grignard reagents, and steric hindrance of the substrates. Our study provides an efficient access to some useful
描述了基于碳钯化、钯催化交叉偶联和 CH 活化的 (E)-1,2-二溴乙烯与受阻格氏试剂的钯催化多米诺反应。这些多米诺反应可能受到配体、反应温度、格氏试剂的亲核性和底物的空间位阻的影响。我们的研究提供了对一些有用的多取代茚和顺式取代茋的有效途径,并且可能有助于开发其他交叉偶联和基于 CH 活化的串联/多米诺反应。
