Hydroalumination Reactions in Organic Chemistry

摘要

Aluminum is the most abundant metal in the earth's crust (82 g centre dot kg~(-1)) and is extensively used in daily life,thus making it an ideal choice for use in organometallic compounds.Since the discovery of Ziegler and Natta that aluminum compounds play a crucial role in polymerization reactions,many aluminum compounds have become available on an industrial scale.As a result,the chemistry of organoaluminum compounds has found widespread use for a variety of such materials.In particular,methylalumoxane (MAO),an important polymerization cocatalyst,has been the subject of recent interest and its chemistry has been reviewed.The present article will give a brief overview of the chemistry of R_2A1H and RA1H_2 compounds,but will concentrate on hydroalumination reactions.
