Abstract
Reaction of highly-substituted bornane-2-selones with a diazoalkane in the presence of either Rh2(OAc)4 or CuCl formed sterically-crowded exo-methylenic products, and similar treatment of the thiones or selones with dihalocarbenes or a propadienylidene carbene also formed dihaloalkenes, butatrienes, and thioketenes. All these reactions were assumed to proceed through a pathway involving the in situ formation and subsequent ring closure of chalcogenocarbonyl ylides.
