The thermal behavior of cis-bicyclo[6.2.0]deca-4,9-diene (55) has been investigated, with the finding that a Cope rearrangement occurs in its overall transformation. When cis-bicyclo[6.2.0]deca-4,9-diene (55) is heated in the vapor phase at 200°C for 1 hour, a 95% conversion into 3,4-divinylcyclohexene (57) takes place, presumably via Cope rearrangement of the intermediate cyclodecatriene 56 (Scheme 14).[‌23‌]
