Beschreibung

Allgemeine Beschreibung

4-Bromo-2,6-di-tert-butylphenol is a 4-substituted-2,6-di-tert-butylphenol. It is synthesized by the bromination of 2,6-di-tert-butylphenol. The structure was confirmed by ¹H NMR. Its photolysis reaction in benzene solution has been investigated. The photochemical reaction of 4-bromo-2,6-di-tert-butylphenol single crystals doped with 2,6-di-tert-butyl-p-quinone has been studied by EPR spectroscopy.

Anwendung

4-Bromo-2,6-di-tert-butylphenol may be used in the following studies:

• As a terminating comonomer phenol in the phase transfer catalyzed (PTC) polymerization of 4-bromo-2,6-dimethylphenol.
• Synthesis of 1,1-[1,10-decanediylbis(oxy)]bis[(2,6-ditertbutyl-4-bromo)benzene], a monomer, which forms poly(p-phenylenevinylene) derivatives by reaction with 1,10-dibromodecane.
• As a reactant in the synthesis of 2,6-di-tert-butyl-phenolnorbornene (N_ArOH), a norbornene comonomer bearing an antioxidant hindered phenol.
• As a catalyst with methyl aluminium to form methylaluminum bis(4-bromo-2,6-di-tert-butylphenoxide) (MABR) which may be utilized for the transformation of various epoxides to carbonyl compounds.
