- γ-hydroxypropylation of 2,6-dialkyl(aryl)phenols with allyl alcohol and its derivatives
-
The composition of the products of the reaction of 2,6-disubstituted phenols with allyl alcohol and its derivatives in an alkaline medium was investigated, the conditions for carrying out the reaction with the predominant formation of 4-(3-hydroxypropyl)-2,6-dialkyl(aryl)phenols were found, and its mechanism was suggested. The reaction was examined on an industrial scale. An important result is the practical demonstration of alkaline catalysis performed under homogeneous conditions with participation of phenols, when the used alkaline catalyst is recovered in the process without the formation of waste waters.

- Synthesis and antioxidant properties of sodium S-[3-(hydroxyaryl)propyl] thiosulfates and [3-(hydroxyaryl)propane]-1-sulfonates
-
Sodium S-[3-(hydroxyaryl)propyl] thiosulfates and [3-(hydroxyaryl)propane]- 1-sulfonates with various spatial hindrance of their phenolic OH groups were synthesized from dialkylphenols via a number of intermediate products. On a model reaction of oxidation of methyl oleate in aqueous sodium dodecyl sulfate, the rate constants of the interaction of the synthesized compounds with lipoperoxide radicals were determined.
