- Gas-Chromatographic identifi cation of products formed in iodination of methyl phenols by retention indices
-
Iodination reaction followed by conversion of iodine-substituted methylphenols to the corresponding trifl uoroacetates was suggested for improving the sensitivity of the gas-chromatographic determination of phenol and its methyl-substituted derivatives (al isomers of mono- and diethylphenols, 2,3,5-, 2,3,6-, and 3,4,5-trimethylphenols) in aqueous media. Acylation products of iodo methylphenols (104 compounds) were identifi ed by linear-logarithmic retention indices on a standard nonpolar polydimethylsiloxane stationary phase, and the pattern of their variation with the number and nature of substituents were characterized. A procedure for identifi cation of methyl-substituted phenols in water in their gas-chromatographic determination with an electron-capture detector was developed. Pleiades Publishing, Ltd., 2012.

- A green reagent for the iodination of phenols
-
A new reagent (I2/NaNO2) for the iodination of the aromatic ring of phenols has been discovered. The reaction proceeds at room temperature in 1.5-6 hours. In the presence of this reagent, iodinated compounds are regioselectively formed in significant yields from the corresponding substrates. Georg Thieme Verlag Stuttgart.

- Iodination of Thallium(I) salts of Phenols
-
The iodination of thallium(I) salts of phenols is examined and the results are compared with those of the selective ortho-iodinating reagent thallium(I) acetate-iodine.
