✦ Synopsis
Ben@ chloride and bromide react with alumina via a two-step mechanism to produce dibenzyl ether in good yield. Chemisorbed benzyloxy is the other major product of the reactions.
The surfaces of inorganic oxides such as alumina, silica gel, clays, and zcolites provide unusual environments for chemical transformations.'
Alumina is particularly interesting in this regard because its surface is polaf and contains immobile, catalytic BrBnsted and Lewis acidic (OH, Al+') and basic
