Facile and efficient synthesis of fluoroalkyl aryl ethers
A convenient and practical method for the preparation of fluoroalkyl aryl ethers via substitution of iodoalkyl fluorides is described. This method involves KF complexation of the phenol, which increases the nucleophilicity of oxygen for the formation of the ether linkage.
CONDENSATION OF 1,2-DIBROMOTETRAFLUOROETHANE WITH VARIOUS POTASSIUM THIOPHENOXIDES AND PHENOXIDES
BrCF2CF2Br reacts easily with various potassium thiophenoxides and phenoxides to give respectively 2-bromo tetrafluoroethyl thioethers and ethers.The lipophilicity of C6H5SCF2CF2Br and C6H5OCF2CF2Br is measured and compared with that of the well known C6H5SCF2CF2H and C6H5OCF2CF2H.
