An efficient procedure is presented for the alkoxycarbonylation of industrially important amines using environmentally friendly alkyl carbonates as reagents and Zn4O(OAc)6 as catalyst. Aromatic amines in particular (thirteen examples) consistently give high yields (up to 98%), regardless of the electronic properties of the substituents or the ring substitution pattern.
