Participants

Reaction Steps

3.3 g (0.013 Mol) SnCl4 is added to 64 g (0.5 Mol) butyl acrylate and dissolved with stirring. Then during cooling to 20° to 25° C., 34 g (0.5 Mol) furane is added drop-wise. The exothermic reaction finishes after one hour, after which stirring is continued for one hour at 25° C. and 30 g of water added. The organic phase is separated. First, the unconverted furane is distilled off under a pressure of 10 Torr, and then the residue is distilled under a pressure of 0.02 Torr. The 2-carbobutoxy-7-oxabicyclo(2.2.1)hept-5-ene boils at 65° C. and is obtained in a yield of 34.3 g (35% of the theoretical).
