Metal-assisted activation of the C–O bond of 2-hydroxyethylmethacrylate. Synthesis and molecular structure of Ti5(OPri)9(µ-OPri)(µ,η2-OC2H4O)(µ3,η2-OC2H4O)3(µ4,η2-OC2H4O)

Ti5(OPri)9(µ-OPri)(OC2H4O)5 is formed by the reaction between Ti(OPri)4 and 2-hydroxyethylmethacrylate in toluene at room temperature; the pentanuclear aggregate is asymmetric with the titanium atoms displaying coordination numbers of five, six and seven.
