Abstract

Das genannte, nicht ebene, Dicarbonsäureanhydrid liefert mit Acetanhydrid unter Einebnung an C-3 a das Ketenacylal3 a. Mit Keten (2 Mol) erhält man aus der Dicarbonsäure1 das gemischte Anhydrid9 a. Weitere Derivate des 1-Oxo-2-oxa-phenalens werden beschrieben.

The reaction of nonplanar 1.2.3.4-tetrahydro-naphthalin-dicarboxylic-(1.8)anhydride with acetic anhydride yields the planar “ketene acylal”3 a. From the dicarboxylic acid1 one obtains with 2 moles of ketene the mixed anhydride9 a. Further derivatives of 1-oxo-2-oxa-phenalene are described.
