Intramolecular Quinhydrones. II. Synthesis and Oxidation Characteristics of Unsymmetrically Bridged DihydroquinonesBy ether cleavage with AlCl3 or AlBr3 the synthesized unsymmetrically bridged tetramethoxy derivatives 2a-w were converted into the corresponding tetravalent hydroquinones 3a-r and these were oxidized to the yellow diquinones 4a-p or partially to the deeply coloured intramolecular quinhydrones 6a-o.
Notes:
Die synthetisierten unsymmetrisch verbrückten Tetramethoxyderivate 2a-w wurden durch Ätherspaltung mit AICl3 oder AlBr3 in die entsprechenden tetravalenten Hydrochinone 3a-r übergeführt und diese zu den gelben Dichinonen 4a-P oder partiell zu den tieffarbigen intramolekularen Chinhydronen 6a-o oxidiert.
