摘要: Dihalocarbenes (:CCl2, :CBr2, and :CI2) add preferentially to one of the radial double bonds corannulene, rather than rim. These cyclopropanations strongly resemble additions dihalocarbenes fullerenes, which likewise occur at 6:6-double bonds, destroy cyclic conjugation in two adjacent benzene rings, give ‘closed’ adducts. An explanation is offered for abnormally high reactivity interior carbon atoms corannulene.
