Patent ID: 7348445

Claim:
A process for the production of an organoaluminum precursor compound represented by the formula wherein R 1 , R 2 , R 3 and R 4 are the same or different and each represents hydrogen or an alkyl group having from 1 to about 3 carbon atoms, and R 5 represents an alkyl group having from 1 to about 3 carbon atoms, which process comprises (i) reacting an organodiamine compound with a base material in the presence of a solvent and under reaction conditions sufficient to produce a first reaction mixture comprising an organodiamine salt compound, (ii) preparing a second reaction mixture by adding an aluminum source compound to said first reaction mixture, (iii) heating the second reaction mixture to reflux for a period of time sufficient to produce a third reaction mixture comprising said organoaluminum precursor compound, and (iv) separating said organoaluminum compound from said third reaction mixture.
