Department of Chemistry, Faculty of Science, Shahid Bahonar University, P.O. Box 76169, Kerman, Iran


Dimerization and 1,3-dipolar cycloaddition reactions of isoquinolinium ylidewith isoquinolinehave been investigated to prepare diaza-dibenzo compounds in good to excellent yields and in a short reaction time. These reactions occur in the presence of base catalyst such as triethylamine at room temperature.
