The major decomposition pathway involved in the fragmentation of derivatives of the title ring systems was the loss of RCN from the five‐membered ring, except when this ring had a 3‐amino,3‐hydroxyl or 3‐mercapto substituent. In these cases, the exocyclic substituent and at least one nitrogen atom from the five‐membered ring were lost.
