Abstract

Abstract: A novel hypervalent iodine induced nucleophilic substitution ofpara-substituted phenol ethers in the presence of a variety of nucleophiles is described. UV and ESR spectroscopic studies indicate that this reaction proceeds via cation radicals,[ArH*+], as reactive intermediates generated by single-electron transfer (SET) from a charge-transfer (CT) complex of phenol ethers with phenyliodine (II1) bis (trifluor0acetate)(PIFA). This is ...
