From Lithium Bis(trimethylsilyl)amide with Cyanoamine into Triazine Compounds: Synthesis and Structures of Lithium 6-((Trimethylsilypamido)-2,4-bis(dimethylamino)[1,3,5]triazines and Their Manganese and Cobalt Complexes
Addition reactions of lithium bis(trimethylsilyl)amide with dimethylcyanamide lead to novel lithium salts of 6-((trimethylsilyl)amido)-2,4-bis(dimethylamino)[1,3,5]triazines [LLi(D)](2) (L = NC(NMe2)NC(NMe2)-NC(NSiMe3); D = Me2NCN (1), Et2O (2)) and to the Mn and Co complexes [LL'M] (L' = N{N(SiMe3)C(NMe2)}(2); M = Mn (3), Co (4)); the structures of crystalline 1, 3, and 4 are reported. Their formation involves trimethylsilyl shifts, ring formation, and unusual Me2NSiMe3 elimination.
