2-methylideneoxolane

Conditions: temp:75.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A stirred mixture of 20.0 g of 2-methylenetetrahydrofuran, 17.7 g of reagent grade methacrolein and 0.4 g of potassium carbonate was maintained at 75° C. under nigrogen atmosphere for 7 days. Distillation of the reaction mixture yielded 19.1 g of the desired product, b.p. 65°-66° C. (4 torr.). Distillation of the reaction mixture
