The composition of the products from the reaction of α-bromocyclopropyllithium compounds with carboxylic acid chlorides and esters is determined by the transformations of the cyclopropyllithium enolates formed as a result of rapid halogen-lithium exchange between the initial organolithium compounds and the intermediate α-bromocyclopropyl ketones.In the case of the aliphatic carboxylic acid derivatives the main competing process is deprotonation of the substrate by the α-bromocyclopropyllithium reagent.
