Free Radical-Mediated Vinyl Amination:  Access toN,N-Dialkyl Enamines and Their β-Stannyl and β-Thio Derivatives

The first examples of free radical-mediated vinyl amination are described by nonconventional vinyl radical addition to azomethine nitrogen. This new vinyl amination protocol is mild and provides convenient synthetic access to nonstabilized N,N-dialkyl enamines and tandem bond-forming processes.
