Methacrylic Acid → Oxolan-2-yl 2-methylprop-2-enoate

Participants

Reaction Steps

To a solution of 10 g methacrylic acid in 10 ml dichloromethane was added a solution of 9.28 ml 2,3-dihydrofuran in 30 ml dichloromethane. The reaction was allowed to stir for 14 hr at room temperature. The mixture was washed with a saturated solution of sodium bicarbonate. The organic layer was dried with MgO/MgSO4 and concentrated in vacuo. The residue was distilled at 38° C./0.3 torr, to give 6.2 g (34% yield) of tetrahydrofuran-2-yl methacrylate. A solution of 6.0 g tetrahydrofuran-2-yl methacrylate and 0.066 g AIBN in 6 ml of MEK was heated to 60° C. for two days and 12 ml of MEK was added. This solution was used for further evaluation.
