Oxime and hydroxylamine derivatives of metals are of current interest [11. Chelating oximes such as amidoximes [2], R (Hz N) C= N-OH, were synthesized during the end of the last century, but little attention was given to their metal derivatives apart from their analytical applications [3-53. We report the synthesis of new mono-, bis-and tris-(trimethylsilyl) amidoximes. Trimethylchlorosilane reacted readily at room temperature with amidoximes, ...
