资源简介:
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.
