Pyrolysis at 200 deg C and direct and sensitized photolysis of the title compound (3a) produced only cis-1,3-divinylcyclobutane (6a) and tricyclo2,5>octane (7a).The latter hydrocarbon was preapared by an independent synthesis, which inv

At 300 deg C cis-1,3-divinylcyclobutane (4) gives butadiene (5) and 4-vinyl-1-cyclohexene (6) as well as trans-1,3-divinylcyclobutane (2) in small quantity. 2 has been synthesized in an independent way and yields the same products as 4.The diradical 3 is

The title compound 7 is obtained by ozonolysis of bicyclohex-2-ene (5) and Wittig reaction of the dialdehyde 6.There was no intramolecular photo-cycloaddition observed by irradiation of 7 but rearrangement to cis- and trans-allylvinylcyclopropanes 10 and 11.With the esters 12 - 14 the light energy is wasted in cis-trans-isomerisations.In comparison, the cis-1,3-cyclopentane derivatives 16 and 17 give some cycloaddition.
