Aluminium iso-Propoxide(AIP)

Product: Aluminium iso-Propoxide(AIP)

Aluminium isopropoxide is the chemical compound usually described with the formula Al(O-i-Pr)3, where i-Pr is the isopropyl group (CH(CH3)2). This colourless solid is a useful reagent in organic synthesis.

Aluminium isopropoxide can also be used as catalyst and curing agent for inks and adhesives

In a MPV reduction, ketones and aldehydes are reduced to alcohols concomitant with the formation of acetone. This reduction relies on an equilibrium process, hence it produces the thermodynamic product. Conversely, in the Oppenauer Oxidation, secondary alcohols are converted to ketones,[8] and homoallylic alcohols are converted to α,β-unsaturated carbonyls.[8] In these reactions, it is assumed that the tetrameric cluster disagregates.

Being a basic alkoxide, Al(O-i-Pr)3 has been also investigated as a catalyst for ring opening polymerization of cyclic esters.
