substituents of the cyclopropene ring. Product composition is markedly influenced by the number, nature, and position of the substituents, which determine the regio- and stereoselectivity of the cyclopropene-ring cleavage. A mechanism is proposed in which attack of the electrophilic RhII species is concerted with disrotatoryringopening of the incipient cyclopropyl cation and affords a metal-complexed
