56.4 g of norbornene, 16.8 g of acrolein and 0.5 g of hydroquinone were heated 15 hours at 190° in a stainless steel autoclave (pressure about 15 atm.). After evaporation a fractional distillation of the residue gave 22.5 g (yield 49%) of 3-oxa-tricyclo[6.2.1.02,7 ]undec-4-ene; b.p. 35°-7°/0.5 Torr.
