6-diisopropylaniline with KN(SiMe3)2 in toluene at 100 °C yields [KN(H)Dipp}] (5), which reacts with CaI2 to give [(thf)nCaN(H)Dipp}2] (6), [(pmdeta)CaN(H)Dipp}2] (7), and [(dme)2CaN(H)Dipp}2] (8), depending on the solvents and coligands. Excess potassium 2,6-diisopropylphenylamide allows the formation of the calciate [K2CaN(H)Dipp}4]∞ (9). Hydroamination of diphenylbutadiyne with 2,6-diisopropylaniline
