Abstract

The reactivity of o‐quinones and other 1,2‐diones towards a variety of dipolar species viz‐, nitrile oxides, carbonyl ylides, betaines and mesoionic compounds has been investigated. In most cases, these reactions occur with the participation of C=O group as the dipolarophile leading to the synthesis of novel heterocyclic compounds.
