Various synthetic approaches to fluoroalkyl p-nitrophenyl ethers
摘要:
Homologous 1H,1H-perfluoroalkyl p-nitrophenyl ethers (alkyl = C-2-C-8) 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 triflates are found and discussed. The preferred synthesis includes the use of trifluoromethane sulphonic acid esters.
