Abstract A general strategy for the assembly of previously unknown tris (β, β, γ-oximinoalkyl) amines from aliphatic nitro compounds and methyl vinyl ketone is described. The strategy involves N, N-bis (siloxy) enamines as key intermediates. The latter are accessible by double silylation of alkylnitro compounds. Nickel (II) and copper (II) complexes of tris (β, β, γ- oximinoalkyl) amines are prepared and structurally characterized.
