FeCl2 catalyzes the oxidative C−C cross-coupling of tertiary amines with terminal alkynes into propargylamines using (t-BuO)2 as oxidant. The reaction can be applied to aromatic and aliphatic amines and alkynes without solvent. High chemoselectivity for aminomethyl groups is due to a steric factor.
