✦ Synopsis

A New and Convenient Synthesis of 1,2-Dioxobenzocyclobutene via Photodecarbonylation.

-Starting from the commercially available ninhydrin (I) a novel synthesis of benzocyclobutenedione (V) via photodecarboxylation of the bisacetal (III) is described. Interestingly, (III) can be easily prepared from (I) contrary to earlier reports. -(LEINWEBER, D.;
