摘要

The reaction of aniline ArNH2 (ArNH2 = 2,6-(CHPh2)2-4-CH3-C6H2NH2) with Lewis acids GaX3 (X3 = Cl3, MeCl2, Me3) leads to the formation of the adducts [ArNH2GaCl3] (1), [ArNH2GaMeCl2] (2), and [ArNH2GaMe3] (3) in high yields. The thermal decomposition of 3 affords amide [ArNHGaMe2]n (n = 1, 2), which further decomposes to form an amorphous compound containing predominantly carbon (89.4% C and 10.6% Ga). The newly synthesized compounds were characterized by X-ray diffraction analysis, NMR and IR spectroscopy, and elemental analysis. Their electronic structures and the proposed reaction pathways were probed in terms of the density functional theory. The thermal stability of products 1–3 was studied by thermogravimetric analysis. The surface composition of the thermal decomposition product was determined by energy-dispersive X-ray spectroscopy.
