Patent ID: 7098339

Claim:
A process for preparing an organometallic compound represented by the formula H 3 Al:L n wherein L is one or more Lewis bases capable of providing an unshared electron pair to the aluminum and n is 1 or 2, said process selected from the following: (1) a process for preparing said organometallic compound comprising (a) forming a first solution of an alkali metal aluminum hydride and a Lewis base in an ethereal solvent, (b) adding to said first solution an aluminum halide in an ethereal solvent under reaction conditions sufficient to produce a second solution comprising said organometallic compound, and (c) separating said organometallic compound from said second solution; (2) a process for preparing said organometallic compound comprising (a) forming a first solution of an aluminum halide and a Lewis base in an ethereal solvent, (b) adding to said first solution an alkali metal aluminum hydride in an ethereal solvent under reaction conditions sufficient to produce a second solution comprising said organometallic compound, and (c) separating said organometallic compound from said second solution; and (3) a process for preparing said organometallic compound comprising (a) reacting an aluminum halide and an alkali metal aluminum hydride in the presence of an ethereal solvent and under reaction conditions sufficient to produce a first solution, (b) adding to said first solution a Lewis base optionally in an ethereal solvent under reaction conditions sufficient to produce a second solution comprising said organometallic compound, and (c) separating said organometallic compound from said second solution.
