Conversion of dinitrogen to tris(trimethylsilyl)amine catalyzed by titanium triamido-amine complexes

By using a triaryl-Tren ligated titanium dinitrogen complex, K-2[{(Xy-N3N)Ti}(2)(l(2)-N-2)] (3), prepared by two-electron reduction of [TiCl(Xy-N3N)] (1-Cl) under N-2 atmosphere, catalytic fixation of molecular nitrogen to form tris(trimethylsilyl) amine was achieved under ambient conditions with a turnover number (TON) of up to 16.5 per titanium atom.
