Abstract
TBAI as catalyst and TBHP as oxidant enable a metal-free cross-coupling of enamines and electron-deficient amines through oxidative C(sp2)-N bond formation. This efficient organocatalytic synthesis of synthetically useful diaminoalkene derivatives features readily available starting materials and wide substrate scope.
