Reactivity of Organogallium−Amine Adducts and Gallium Amides toward Some Nonhydrolytic Gel Precursor Mixtures
The synthesis and spectroscopic and structural characterization of some new amine−gallane adducts as well as gallium amides are described.

| description | The synthesis and spectroscopic and structural characterization of some new amine−gallane adducts as well as gallium amides are described. This work was carried out in order to test their reactivity as gallium nitride precursors toward nonhydrolytic gel precursor mixtures. These mixtures usually consist of M(OR) n /M‘Cl n (M or M‘ = B, Al, Si, or Ti) species combined in various proportions. It was found that the adduct Me3GaNH(i-Pr)2 reacts with SiCl4 to form compounds with gallium−chlorine bonds and up to three chlorines may be substituted at gallium. The gallium amide (Me2GaNPh2)2 also reacts with SiCl4 to give a chlorinated species. The only amide precursor species that proved inert to SiCl4 was the sterically encumbered derivative Ga{N(SiMe3)2}3 which could be isolated unchanged after several days reaction time. In addition, the compound {TiCl3OEt} n was isolated from a Ti(OEt)4/SiCl4 reaction system and structurally characterized. |
