3,5-Di-tert-butyl-o-benzoquinone was used in the preparation of benzoxazoles derivative ligands. It was also used in the preparation of 1,4-benzodioxines via hetero Diels Alder reaction with acyclic dienes.
4,6-Di-tert-butyl-1,2-benzoquinone is a Ortho-Quinone derivative is know to possess a number of biological properties such as antitumoral, antimicrobacterial and anti-cardiovascular disease.
Reactions of the phosphinidene-bridged complexes [Fe2(η5-C5H5)2(μ-PR)(μ-CO)(CO)2] (R = Cy, Ph) with 3,5-di-tert-butyl-o-benzoquinone has been reported.
It can be recrystallised from MeOH or pet ether, and forms fine red plates or rhombs. [Flaig et al. Justus Liebigs Ann Chem 597 196 1955, IR: Ley & Müller Chem Ber 89 1402 1956, Beilstein 7 IV 2113.]
