Reaction of Nitroegn(I) Oxide with Nitrogen-fixing Systems on the Basis of Lithium, Chlorotrimethylsilane, and Transition Metal Compounds

摘要

Reaction of nitrogen(I) oxide with nitrogen-fixing system Li/Me_3SiCl/MCl_n (MCl_n = CrCl_3, CoCl_2, Cp_2TiCl_2, FeCl_3, CuCl_2) was studied. In these systems nitrogen(I) oxide, molecular nitrogen, and air nitrogen undergo reductive silylation to tris(trimethylsilyl)amine. The efficiency of the process was estimated by the molar ratio of the tris(trimethylsilyl)amine formed to metal chloride MCl_n. The reaction of N_2O with the nitrogen-fixing systems including CoCl_2 and Cp_2TiCl_2 is not exhausted by the reduction of the former to molecular nitorgen and its subsequent fixation by transition metal complexes.
