The C-C bond forming catalytic 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 corresponding linear hydroaminoalkylation products with excellent regioselectivities.
末端烯烃、1,3-二烯或苯乙烯的 C-C 键形成催化氢氨基烷基化反应允许直接且高效原子经济性(100%)合成胺,这可能导致两种区域异构体的形成,即直链和支链产物。我们提出了一种新的钛催化剂,带有 2,6-双(苯氨基)吡啶并配体,用于苯乙烯和 1-苯基-1,3-丁二烯的分子间氢氨基烷基化反应,可获得具有优异区域选择性的相应线性氢氨基烷基化产物。
