An in situ formed palladium hydride catalyst enables the sequential dual isomerization of propargylamide derivatives to 1-amido-1,3-dienes with high chemo- and regioselectivity. The reaction shows ample functional group tolerance, delivering a valuable class of products, including highly deuterated ones, from readily available reagents. The reaction occurs through a complex mechanism studied by DFT
一个原位形成氢化物的钯催化剂使炔丙基酰胺衍生物的1酰氨基1,3-二烯与高化疗和区域选择性顺序双异构化。该反应显示出足够的官能团耐受性,可以从现成的试剂中提供有价值的一类产品,包括高度氘化的产品。反应是通过DFT建模研究的复杂机制发生的。
