Synthesis of 4-(ω-hydroxyalkyl)-2,6-di-tert-butylphenols and the properties of related sulfides

Reaction of 2,6-di-tert-butylphenol with aliphatic linear and branched diols in an alkaline medium at a temperature of 180-220°C leads to the formation of 4-(ω-hydroxyalkyl)-2,6-di-tert-butylphenols. The increase in the product yield and reducing the reaction temperature was reached at the catalysis of this reaction with zinc oxide. The structure of the diphenylalkane derivatives generated in side reaction was proved and the structural influence of the length of the aliphatic residue on the antioxidant effectiveness of the sulfides derived from the corresponding hydroxyalkylphenols was examined.

Radical ion probes, 8. Direct and indirect electrochemistry of 5,7-di-tert-butylspiro[2.5]octa-4,7-dien-6-one and derivatives

Results pertaining to the direct and indirect electrochemistry of 5,7-di-tert-butylspiro[2.5]octa-4,7-dien-6-one (1a), 1-methyl-5,7-di-tert-butylspiro[2.5]octa-4,7-dien-6-one (1b), and 1,1,-dimethyl-5,7-di-tert-butylspiro[2.5]octa-4,7-dien-6-one (1c) are reported. Product analyses reveal that reduction of all these substrates leads to cyclopropane ring-opened products; ring opening occurs with modest selectivity leading to the more substituted (stable) distonic radical anion. The direct electrochemistry of these compounds is characterized by rate limiting electron transfer (with α ~ 0.5), suggesting that while ring opening is extremely rapid, the radical anions do have a discrete lifetime (i.e., electron transfer and ring opening are not concerted). Utilizing homogeneous redox catalysis, rate constants for electron transfer between 1a, 1b, and 1c and a series of aromatic radical anions were measured; reduction potentials and reorganization energies were derived from these rate constants by using Marcus theory.
