Aluminum–Amido-Mediated Heterolytic Addition of Water Affords an Alumoxane

Addition of the O–H bonds in water across the aluminum–nitrogen bond of a molecular aluminum–amido complex affords an alumoxane. The reaction of (PhI2P2–)­AlH (1) with water forms dimeric [(PhHI2P–)­AlH]­(μ-O) (2) under mild conditions. Upon reaction of 2 with excess water [(PhHI2P–)­Al­(OH)]­(μ-O) (3) is formed with liberation of H2.
