Aminoalkoxo-supported heteroleptic hexanuclear gallium(iii) wheel as a synthon for group 13 heterometallics: A rare sol–gel precursor for mixed Al–Ga oxide as support for goldcatalysts

Abstract

A new heteroleptic gallium(III) complex, Ga₆Cl₆(mdea)₆ (1·2CHCl₃) (mdeaH₂ = N-methyl diethanolamine) was prepared in good yield by a chloro-aminoalkoxo exchange reaction and used as a synthon for the synthesis of a novel group 13 heterometallic derivative, Ga₂Al₄(O)₂(mdea)₂(OPrⁱ)₁₀ (2·2CHCl₃), the latter acting as a facile single source precursor for the sol–gel preparation of the mixed Al–Ga oxide as a high surface area support for gold catalysts.
