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

A number of mesoionic compounds derivatives of the bicyclic system 1,3,4-triazolo(3,2\_a)pyridine have been prepared, and an improved method for the preparation of 1,3,4oxadiazolo(3,2-a)pyridylium-2-aminides from 1,3,4-oxadiazolo(3,2-a)pyridylium-2-olate and iminophosphoranes is described. Recently
