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 tBu2SbCl as reagent, a tert-butyl-substituted stibano amine tBu2SbN(H) tBu ( 1), an isopropyl-substituted interpnictogen tBu2SbN(H) iPr ( 2), and a primary stibano amine tBu2SbNH2 ( 3) are obtained. Condensation of compound 3 leads to compound ( tBu2Sb)2NH ( 4) with elimination of ammonia. All compounds were characterized by 1H, 13C, 15N 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 [ tBu2SbN(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. [ABSTRACT FROM AUTHOR]
