Abstract

<jats:title>Abstract</jats:title> <jats:p>Irradiation of indane-1,2,3-trione in degassed alcoholic solutions affords 3-alkoxycarbonylphthalides as the major product together with 3-alkoxyphthalides. 3-Alkoxycarbonylphthalides may be derived from the reaction between alcohols and the spirooxiranone intermediate, generated photochemically by cleavage of the bond between two carbonyl groups of indane-1,2,3-trione via a cyclobutenone biradical derivative.</jats:p>
