The gold-catalyzed hydration of 2-phenyl- or 2,2-diphenylcyclopropyl acetylene, sensitive probes to trace the formation of vinyl carbocations, provides exclusively the corresponding cyclopropyl methyl ketones. On the other hand, in the Ag(I)- or Fe(III)-c

The reaction of a series of α-bromocyclopropyl ketones substituted in the three-membered ring with triphenylphosphine in alcohols in the presence of catalytic amounts of hydrochloric acid leads to the formation of the products from opening of the cyclopropane ring.Under analogous conditions 1-benzoyl-1-bromocyclopropane undergoes reductive dehalogenation.In boiling methanol 7-exo-benzobicycloheptane is converted into trans-1-bromo-2-benzoylmethylcyclohexane by the action of a mixture of triphenylphosphine and 1-benzoyl-1-bromocyclopropane and also by a mixture of triphenylphosphine and carbon tetrabromide.
