text: Organoaluminium compounds are extremely pyrophoric and are handled only under inert atmospheres. Dialkylaluminium hydrides and lithium aluminium hydride are both available commercially; the former is available either neat or in solutions that may be standardized using known procedures. Solvents and other reagents should be scrupulously dried. Workup of these reactions should employ extreme pH's (10% hydrochloric acid or 6 N sodium hydroxide), as moderate pH encourages the formation of gelatinous aluminium hydroxide, which renders product separation difficult.
