Tris(diethylamino)bismuthine (I) reacted with the sterically unhindered carbonyl compounds to give the corresponding enamines. The reactivity of the metal amides M(NR2)n (M=As, Sb, Bi, and Ti; R=Me and Et) toward the carbonyl compounds was examined. The order of reactivity: Bi>Sb>Ti>As was observed for the addition reaction that took place as the first step in the reaction. On the other hand, the order of enamine formation was Sb>Ti>As>Bi. The effectiveness of the amination reaction depends both on the reactivity of metal amides to carbonyl groups and also on the affinity for oxygen of metal atoms. Although bismuth amide gives the addition product very rapidly, because of its poor affinity for oxygen, the addition products decompose thermally on prolonged standing or on distillation giving large amounts of starting carbonyl compounds along with small amounts of enamines.
