An efficient para-alkylation of primary and secondary anilines with a variety of sterically encumbered alkenes using a simple β-diketiminato scandium catalyst is reported. This protocol features 100% atom economy, excellent chemo- and regioselectivity, broad substrate scope, and good functional group tolerance. Mechanistic studies disclosed that the reaction probably proceeded via a tandem hydroam
据报道,使用简单的β-二酮亚胺基scan催化剂可有效地将伯和仲苯胺与各种空间受限的烯烃进行对烷基高效烷基化。该协议具有100%的原子经济性,出色的化学和区域选择性,广泛的底物范围以及良好的官能团耐受性。机理研究表明,该反应可能是通过串联加氢胺化/霍夫曼-马修斯重排进行的。
