An interrupted Schmidt rearrangement/Hosomi-Sakurai reaction of N-tosyl and S-substituted vinyl azides is reported. With BF3·Et2O as a Lewis acid promoter, the denitrogenative fragmentation of vinyl azides facilitates the generation of the N/S-stabilized carbocations, which further undergo nucleophilic addition by allyl/propargylsilanes for C-C bond formation. As a result, a variety of homoallylic/allenylic amines can be afforded in good yields under mild reaction conditions with well-defined functional-group tolerance.

Selenlranlum Ions at low temperatures (-90 to -78 0C) will initiate effective Frledel-Crafts cycllzatlon If a suitably placed arene is allowed to react even when the arene is unactivated. These intermediates generated from N-aryl-W-tosylamides undergo a n
