Synthesis and Reactions of Organic Compounds

Abstract The nucleophilic substitution of a number of di- and trisubstituted fluoroarenetricarbonylchromium complexes has been studied using the alkoxides derived from methyl, ethyl, isopropyl and t-butyl alcohols. In the first three cases the reactions proceed smoothly to give the expected aryl ethers, while in the t-butoxide case significant amounts of phenolic elimination products are also observed. Fluoride was displaced from arenes containing alkyl, methoxy, amino and alkylamino substituents.
