The thermally induced ring opening of 1 and 5 proceeds with found, a behaviour that corresponds with the known photochemistry of cyclobutenes. A surprising reaction was high stereospecifity in a conrotatory fashion in agreement with the Woodward-Hoffmann rules. Upon flash pyrolysis of found if 1 and
