Reactions with Diazocarbonyl Compounds, XXXI V I ). o-Quinone Diazides and o-Quinones as Dehydrobenzene InterceptorsSuitably substituted o-quinone diazides can be used to intercept arynes with simultaneous N2-elimination and formation of dibenzofuranes. o-Quinones add arynes in a Diels-Alder synthesis to form cyclic diketo compounds, which react with o-phenylenediamine to give the corresponding quinoxalines.
Notes:
Arine lassen sich mit geeignet substituierten o-Chinondiaziden unter N2-Abspaltung und Bildung von Dibenzofuranen abfangen. o-Chinone addieren nach Diels-Alder Arine zu cyclischen Diketo-Verbindungen, die mit o-Phenylendiamin zu den entsprechenden Chinoxalinen kondensieren.
