    Description / Table of Contents: The Photolysis of 2-Diazo-[1-13C]naphthalen-1(2H)-one and 1-Diazo-[1-13C]naphthalen-2(1H)-one. A Contribution to the Xoirene ProblemThe synthesis of 2-diazo-[1-13C]naphthalen-1(2H)-one (10) and 1-diazo-[1-13C]naphthalen-2(1H)-one (16) starting from Ba13CO3 is reported. The photolysis of 10 in dioxan/water (10: 1) leads to [carboxy-13C]indene-1-carboxylic acid (19). Correspondingly 16 yields [1-13C]indene-1-carboxylic acid (23). The absence of any isotope scrambling excludes an oxirene participation in the photolysis of 2- or 1-diazonaphthalen-1(2H)- or -2(1H)-one.
    Notes: Die Synthese von 2-Diazo[1-13C]naphthalin-1(2H)-on (10) und 1-Diazo-[1-13C]naphthalin-2(1H)-on (16) beginnend mit Ba13CO3 wird beschrieben. die Photolyse von 10 in Dioxan/Wasser (10: 1) führt zu [Carboxy-13C]Inden-1-carbonsäure (19). Entsprechend ergibt 16 [1-13C]Inden-1-carbonsäure (23). Das Ausbleiben einer Isotopenverteilung schließt eine Oxiren-Beteiligung bei der Photolyse von 2- bzw. 1-Diazonaphthalin-1(2H)- bzw. -2(1H)-on aus.
