Abstract
The reaction of 3,6-di-tert-butyl-o-benzoquinone with dimedone in the presence of a catalytic amount of Et3N occurs as repeated 1,4-nucleoph ilic addition-oxidation and isomerization of a tricyclic quinone into quinomethane. The intermediate products were isolated and characterize d. Semiquinone complexes of quinones were studied by ESR in solution.
