Abstract
The intermolecular anti-Markovnikov hydroamination of vinylsilanes was achieved utilizing five silyl-substituted ortho-terphenoxide yttrium complexes. The highest activity was observed for the most sterically encumbered triphenylsilyl-substituted complex. Excellent activity and complete anti-Markonikov selectivity were obtained for a variety of benzylic and aliphatic primary and secondary amines. Interestingly, the reaction with 2-picolylamine produced the hydroaminoalkylation product rather than the hydroamination product. Reaction of dimethyldivinylsilane resulted in a range of 1,4-azasilinanes via sequential hydroamination/endocyclization in good yields.
