| Abstract: | Homophthalic acid was reacted with thionyl chloride/DMF and ethyl chloroformate/NEt3 in the presence and absence of NaN3. In all cases completely different isocoumarin derivatives were obtained. These unusual isocoumarin derivatives were characterized and their mechanism of formation is discussed. |
