Abstract [en]

The dynamic exchange of enamines from secondary amines and enolizable aldehydes has been demonstrated in organic solvents. The enamine exchange with amines was efficiently catalyzed by Bi(OTf)(3) and Sc(OTf)(3) (2mol%) and the equilibria (60mm) could be attained within hours at room temperature. The formed dynamic covalent systems displayed high stabilities in basic environment with <2% by-product formation within one week after complete equilibration. This study expands the scope of dynamic C-N bonds from imine chemistry to enamines, enabling further dynamic methodologies in exploration of this important class of structures in systems chemistry.
