General Description

2,5-Di-tert-butyl-1,4-benzoquinone (DTBBQ) is an 2,5-disubstituted quinone. It is an antibacterial compound. It has been isolated from marine Streptomyces sp. VITVSK1. Pressure dependance on the intramolecular and intermolecular migration rates of Na⁺ and K⁺ in a 2,5-di-tert-butyl-1,4-benzoquinone ion pair have been evaluated by using a high-pressure EPR technique.

Flammability and Explosibility

Flammable

Synthesis

At 0 °C, 2,5-di-tert-butylhydroquinone (0.34 mmol) was dissolved in THF (1.0 mL) with Catalyst 2a (1.98 mg, 0.0034 mmol), and 30% aqueous H2O2 (50.0 mL, 0.44 mmol) was slowly added. The reaction mixture was stirred at 0 °C until the raw material was completely converted to 2,5-di-tert-butyl-1,4-benzoquinone. Upon completion of the reaction, the product was extracted with ether or dichloromethane, and the organic phase was dried over anhydrous Na2SO4 and concentrated under reduced pressure to afford the target compound 2,5-di-tert-butyl-1,4-benzoquinone. It is worth noting that the resulting product usually has high purity and can meet the requirements for subsequent use without further purification by column chromatography.
