Aluminium phenolate (original) (raw)

Aluminium phenolate is the metalloorganic compound with the formula [Al(OC6H5)3]n. It is a white solid. 27Al NMR studies suggest that aluminium phenolate exists in benzene solution as a mixture of dimer and trimer. The compound is can be prepared by the reaction of elemental aluminium with phenol: Al + 3 HOC6H5 → Al(OC6H5)3 + 1.5 H2 The compound is used as a catalyst for the alkylation of phenols with various alkenes. For example, the ethylphenols are generated commercially by treating phenol with ethylene in the presence of a catalytic amount of aluminium phenolate.
