Abstract
The dehydrocondensation of 3,6-di-tert-butyl-o-benzoquinone with ethylene glycol, glycerol, its chlorhydrin, and with diethanolamine, catalyzed by MnO2−NaOH, has been carried out in an alcohol-DMF medium with the formation of 7,10-di-tert-butyl-2,5-dioxabicyclo[4.4.0]deca-1,6-diene-8.9-dione, its 4-hydroxymethyl and 4-chloromethyl derivatives, and 7,10-di-tert-butyl-5-(β-hydroxyethyl)-2-oxa-5-azabicyclo[4.4.0]deca-1,6-diene-8,9-dione.
