2.6- Di-r-butylphenol

In structures such as 2,6-di-r-butylphenol, in which steric hindrance prevents hydrogen bonding, no bonded hydroxyl band is observed, not even in spectra of neat samples. 

The nature of the cation (K+ or Na+) in hydroxides has been found to affect the temperature plot of the equilibrium constants of the reaction of KOH and NaOH with 2,6-di-r-butylphenol (ArOH). The nature of the cation in the resulting phenoxides ArOK or ArONa is a factor determining the kinetics of the addition of ArOH to CH2=CHC02Me. Two different kinetic schemes have been proposed to describe the transformation of ArOH in the presence of ArONa or ArOK.137... 

Copolymerization of 4-bromo-2,6-dimethylphenol with 2,4,6-trimethylphenol, 4-t-butyl-2,6-dimethylphenol, 2,2-bis(4-hydroxy-3,5-dimethylphenyl)propane, 4-hydroxy-3,5-dimethylbenzyl alcohol and a 4-substituted-2,6-di-r-butylphenol are discussed269. 

Bis[morpholino] tellurium dichloride in dichloromethane oxidized hydroquinones quickly to quinones, thiols quickly to disulfides, and 2,6-di-r-butylphenol slowly to a dipheno-quinone. The by-products are elemental tellurium and morpholine hydrochloride2. 

Hart and Cassis, Jr. utilized the dechlorination with Raney alloy and alkali in the synthesis of 2,6-di-r-butylphenol from 4-bromo- or 4-chlorophenol as starting mate-... 

In the course of the reaction, the a carbon atom of the radical looses the stereochemistry that it could have had. The chain reaction can be blocked by a radical inhibitor such as 2,6-di-r-butylphenol, because the latter gives a relatively stable ArO radical.
