experimental part, p. 275 - 283 (2010/07/15)
The process of thermolysis of tert-butylated hydroxyalkyl phenols includes de-tert-butylation, etherification, and fragmentation of the hydroxyalkyl group. On the basis of the proposed schemes of the mechanism of thermal de-tert-butylation the path of the search for catalysts for the synthesis of 4-hydroxyalkylphenols is defined and transformations of the by-products into biologically active substances were considered.

Reactions of 4-alkyl-2,6-di-tert-butylphenols containing OH, SH, COOH, and COOMe groups in their para substituents with hydrogen chloride and hydrohalic acids were studied. One-step transformations of 2,6-di-tert-butyl-4-(ω- hydroxyalkyl)phenols to the corresponding 4-(ω-halogenoalkyl)phenols, as well as of 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid and its esters to phloretic acid were proposed. 4-(3-Mercaptopropyl)phenol upon heating with conc. HBr undergoes condensation to 3-(4-hydroxyphenyl)propyl 4-(3-mercaptopropyl)phenyl sulfide as the main product.

The compounds 2'-hydroxy-5'-(hydroxyalkyl)phenyl-2H-benzotriazoles are useful as intermediate alcohols in the preparation of corresponding 2'-hydroxy-5'-acrylyloxyphenyl-2H-benzotriazole monomers, which in turn are copolymerizable with ethylenically unsaturated monomers, particularly acrylic monomers, to impart ultraviolet absorbing properties to the resulting copolymers.
