참여 물질

반응 단계

A three neck round bottom flask containing a teflon coated magnetic stirring bar was successively charged with 95 mL (0.884 mol) of methyl methacrylate (2), 4.22 g (0.012 mol) of titanium tetrabutoxide (Ti(OC4H9)4), 50 mL (0.316 mol) of 3-benzyloxy-1-propanol (1), and 14.6 g (0.073 mol) of 4-benzyloxyphenol (4-BOP). An addition funnel, thermometer, and a short path still head with thermometer and receiver flask were placed in the flask necks. The flask was placed in an oil bath and the temperature was increased until distillation began. Methyl methacrylate (2) was placed in the addition funnel and was added dropwise at the same rate as the distillate. The reaction mixture was heated for 4 hours and then cooled to room temperature. The crude product was vacuum distilled to isolate 36.5 g (0.156 mol, 49%) of 3-benzyloxypropyl methacrylate (3) as a clear, colorless liquid.
