The reaction of AlMe<sub>3</sub> with 3,5-(CF<sub>3</sub>)<sub>2</sub>C<sub>6</sub>H<sub>3</sub>OH at room temperature renders the dinuclear [AlMe<sub>2</sub>(OR)]<sub>2</sub> (<b>1</b>) (OR = 3,5-(CF<sub>3</sub>)<sub>2</sub>C<sub>6</sub>H<sub>3</sub>O), trinuclear {[AlMe<sub>2</sub>(OR)]<sub>2</sub>[AlMe(OR)<sub>2</sub>]} (<b>2</b>), or tetranuclear {[AlMe<sub>2</sub>(OR)]<sub>2</sub>[AlMe(OR)<sub>2</sub>]<sub>2</sub>} (<b>3</b>) derivative depending on the reaction conditions (solvent and stoichiometry of the reagents). All compounds have been characterized by elemental analysis and NMR spectroscopy, and their crystal structures determined by X-ray diffraction methods. Catalytic studies reveal that these compounds show high activity in ring-opening polymerization of cyclohexene oxide (CHO). The activity in the catalytic process varies significantly with solvent and temperature conditions.
