摘要：

We herein describe an accessible ligand-controlled nickel-catalyzed tandem isomerization/regiodivergent hydroheteroarylation of alpha-alkenes with a series of heteroarenes, wherein the NHC ligand of heteroleptic Ni(II) complexes of the type Ni(NHC)[P(OEt)(3)]Br-2 displayed significant effects on regulation. In the presence of (NaOBu)-Bu-t, Ni(IMes)[P(OEt)(3)]Br-2 enables C=C bond isomerization of alpha-alkenes over up to four sp(3) carbon atoms to afford branched products, while Ni(IPr*(OMe))[P(OEt)(3)]Br-2 greatly deactivates alpha-alkene isomerization and favors the formation of linear products.
