The thermodynamical disadvantage of cycloheptene compared with cyclohexane may decelerate the ring opening of cyclopropane. It is also possible that the stereoelectronic effect as shown in the solvolysis of cyclopropyl derivatives inhibits the ring opening when the intermediary carbenium ion 9 attacks 7 from the exo direction. See ref. 12. We can not provide at present a reasonable explanation for the higher reactivity of 7 than 1b.
