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.

The present invention generally relates to a process that selectively polymerizes ethylene in the presence of an alpha-olefin, and to a metal-ligand complex (precatalyst) and catalyst useful in such processes, and to related compositions. The present invention also generally relates to ligands and intermediates useful for preparing the metal-ligand complex and to processes of their preparation.

Two intramolecular routes were experimented to reach the hexahydrobenzofuro[2,3-c]pyridine platform: a Heck and a radical reaction. The radical route was applicable to all substrates, whereas the Heck route was of limited use. The key adducts were obtained via a Mitsunobu condensation between halogenated phenols and an allylic alcohol, the 3-hydroxy-tetrahydropyridine.
