Abstract
Protonation of Na3[Ta(CO)5] in liquid ammonia provides the thermally unstable Na[Ta(CO)5NH3], which may be isolated as the crystalline and deep violet salt [Ph4As][Ta(CO)5NH3]. Sodium amminepentacarbonyltantalate(1-) reacts with PMe3, PPh3, P(OMe)3, AsPh3, SbPh3, CNtBu and CN- at about 0°C in NH3/THF to give exclusively the corresponding [Ta(CO)5L]z. These have been isolated as tetraethylammonium salts in 54-84% yields.
