In this study, mild conditions for aromatic substitutions during the syntheses of aryl ethers were developed. In the reaction conditions, the choices of solvent, base, and the sequence for the addition of the reagents proved important. A wide variety of alcohols were used directly as nucleophiles and smoothly reacted with aryl chlorides that possessed either a nitro or a cyano group at either the ortho- or para-position. Controlled experiments we performed suggested that the reaction underwent a charge-transfer process mediated by a combination of DMF and tert-BuOK.

Various synthetic approaches to fluoroalkyl p-nitrophenyl ethers

, p. 145 - 148 (2007/10/03)
Homologous 1H,1H-perfluoroalkyl p-nitrophenyl ethers (alkyl = C2-C8) were synthesized using different methods. The results are discussed in context with contradictory comments of the literature. The fluoroalkoxylation of p-chloronitrobenzene occurs in only one step, but it is limited to small fluoroalkyl groups. The fluoroalkylation of p-nitrophenol via sulphonic acid esters is a better synthetic route. Differences in reactivity and yield between tosylates, mesylates and inflates are found and discussed. The preferred synthesis includes the use of trifluoromethane sulphonic acid esters.
