The preparation of bicyclo [2.2. 0] hex-1 (4)-ene (1) via ring expansion of a cyclopropylcarbene or the dehalogenation of 1-bromo-4-chlorobicyclo [2.2. 0] hexane is described. It is one of the most reactive of the alkenes which may be observed at room temperature. Its reactions, including dimerization and cycloaddition reactions, are described. The latter lead to convenient preparations of [m. 2.2] propellanes. The vibrational ...
