DOI: 10.1021/acscatal.7b01486
Abstract: The synthesis of a series of structurally varied pyridonate-supported tantalum amido complexes and their catalytic reactivity in the intermolecular α-alkylation of unprotected secondary amines are described. Both terminal and internal alkenes can undergo this hydroaminoalkylation… read more here.

DOI: 10.1021/jacs.2c08039
Abstract: A mild and site-selective hydroaminoalkylation of activated and unactivated alkenes via dual photoredox/Ni catalysis is developed. This dual catalytic strategy enables exclusive access to α-selective products, which is complementary to previously reported photocatalytic hydroaminoalkylation of… read more here.

DOI: 10.1055/s-0036-1589048
Abstract: Vinylsilanes undergo intermolecular alkene hydroaminoalkylation with secondary amines in the presence of a titanium mono(aminopyridinato) catalyst to give the branched hydroaminoalkylation products with high regioselectivity. Corresponding reactions of a suitable (2-bromophenyl)vinylsilane combined with a subsequent… read more here.

DOI: 10.1055/s-0037-1611790
Abstract: The first examples of early-transition-metal-catalyzed hydroaminoalkylation reactions of allenes are reported. Initial studies performed with secondary aminoallenes led to the identification of a suitable titanium catalyst and revealed that under the reaction conditions, the initially… read more here.
