From Lithium Bis(trimethylsilyl)amide with Cyanoamine into Triazine Compounds: Synthesis and Structures of Lithium 6-((Trimethylsilyl)amido)-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(NMe(2))NC(NMe(2))NC(NSiMe(3)); D = Me(2)NCN (1), Et(2)O (2)) and to the Mn and Co complexes [LL'M] (L' = N{N(SiMe(3))C(NMe(2))}(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 Me(2)NSiMe(3) elimination.
