Iridium-Catalyzed C4-Alkylation of 2,6-Di-tert-butylphenol by Using Hydrogen-Borrowing Catalysis

An iridium-catalyzed hydrogen-borrowing process has been developed whereby 2,6-di-tert-butylphenol can be alkylated at the C4-position by using a range of primary alcohols (11 examples, 40-93% yield). Following this, a selection of the products obtained underwent retro-Friedel-Crafts reactions to provide para-substituted phenols, which could potentially undergo further synthetic manipulations.

Development of a one-stage synthesis of 2,6-di-tert-4-ethylbutylphenol from 2,6-di-tert-butylphenol

Investigation of the catalyzed reaction of 2,6-di-tert-butylphenol with ethanol, ethylene glycol, oligomeric glycols, and paraldehyde in a strongly basic medium permitted to develop a technologically suitable procedure for manufacture of 2,6-di-tert-4-ethyl-butylphenol, used in the synthesis of Antioxidant-425.

Perfluoroalkyl substituted hydroxyphenylalkanoic ester antioxidants and stabilized compositions

Perfluoroalkyl substituted neopentyl alcohols can be reacted with substituted hydroxphenylalkanoic esters to form perfluoroalkyl containing hydroxyphenylalkanoic ester antioxidants. The perfluoroalkyl substituted hindered hydroxyphenyl alkanoates are stablizers which confer superior processing stability to polymers processed at elevated temperatures such as polypropylene, as well as protecting said polymers from thermal and oxidative degradation.
