Novel Stibano Amines: Synthesis and Reactivity towards Group 13 Element Organics

In this paper, the syntheses of antimony and nitrogen containing interpnictogen compounds are described. Using tBu(2)SbCl as reagent, a tert-butyl-substituted stibano amine tBu(2)SbN(H)tBu (1), an isopropyl-substituted interpnictogen tBu(2)SbN(H)iPr (2), and a primary stibano amine tBu(2)SbNH(2) (3) are obtained. Condensation of compound 3 leads to compound (tBu(2)Sb)(2)NH (4) with elimination of ammonia. All compounds were characterized by H-1, C-13, N-15 NMR spectroscopy, mass spectrometry, and IR spectroscopy. These interpnictogens represent a new class of single-source precursors for MOVPE process. The primary amine 3 reacts with AlEt3 and GaEt3 to form previously unknown stibane-substituted [tBu(2)SbN(H)MEt2](2) ring compounds [M = Al (5), M = Ga (6)], which were characterized by different spectroscopic methods. Moreover, compounds 4 and 6 could be analyzed by X-ray diffraction.
