hydroaminoalkylation of terminal alkenes, 1,3‐dienes, or styrenes allows a direct and highly atom efficient (100 %) synthesis of amines which can result in the formation of two regioisomers, the linear and the branched product. We present a new titanium catalyst with 2,6‐bis(phenylamino)pyridinato ligands for intermolecular hydroaminoalkylation reactions of styrenes and 1‐phenyl‐1,3‐butadienes that delivers the
与c C键的形成末端烯烃,1,3-二烯,或苯乙烯的催化hydroaminoalkylation允许胺的直接和高度原子效率的(100%)的合成可导致形成两种区域异构体的,直链和支链产物。我们提出了一种新型的带有2,6-双(苯基氨基)吡啶基配体的钛催化剂,用于苯乙烯和1-苯基-1,3-丁二烯的分子间加氢烷基化反应,可提供相应的线性加氢烷基化产物,具有出色的区域选择性。
