Y. Kita et al., HYPERVALENT IODINE REAGENTS IN ORGANIC-SYNTHESIS - NUCLEOPHILIC-SUBSTITUTION OF P-SUBSTITUTED PHENOL ETHERS, Pure and applied chemistry, 68(3), 1996, pp. 627-630
The novel hypervalent iodine-induced nucleophilic substitution of p-su
bstituted phenol ethers in the presence of a variety of nucleophiles a
nd the direct alkyl azidation of p-alkyl phenol ethers are described U
V and ESR spectroscopic studies indicate that these reactions proceed
via radical species; one is [ArH+.] and the other is [ArC(.)R(1)R(2)]
as reactive intermediates.
