Procedure

A mixture of 715 g (7.6 M) of norbornene, 550 g (8.1 M) of isoprene and 2 g of pyrogallol was heated in a stainless steel autoclave at ca. 150° during 15 hours. An internal pressure of 20 atm. is thus reached. The reaction mixture was then distilled by means of a Vigreux column and yielded 467 g (yield 38 %) of 5-methyl-tricyclo[6.2.1.02,7 ] undec-4-ene having b.p. 90°/10 Torr.
