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 intramolecular Buchwald–Hartwig amination result in the development of an elegant one-pot procedure for the synthesis of 1,4-benzoazasilines.
