Organoaluminium compounds have attracted considerable attention as novel reagents in organic syntheses, particularly in aspects of highly selective reactions. Recent studies on synthetic reactions utilizing organoaluminium compounds are briefly reviewed in this paper, which mainly deals with carbon-carbon bond forming reactions in the following topics : [1] Carbon-carbon bond formation; (a) methylation, (b) preparation and reactions of alkenylaluminium compounds-hydroalumination, carboalumination, and conjugate addition, (c) conjugate addition of alkynylaluminium compounds, (d) diastereoselective reactions utilizing allylaluminium reagents, (e) methylenation of carbonyl groups, (f) generation and reactions of aluminium enolates, (g) hydrocyanation. [2] Unique roles as Lewis acid : (a) ene reaction, (b) Diels-Alder reaction, and (c) Claisen rearrangement, [3] Beckmann rearrangement with simultaneous alkylation.
