The effect of different factors (pK a of the base, nature of the counterion and dissociation of the ion pairs) on the course of the base-induced rearrangement of 1,4-dithiins to 1,3-dithiole derivatives is discussed. Ab initio calculations account for the driving force of these isomerisations.

## Abstract A series of 6‐azacytosines **4a‐4k** and **5a‐5c** were prepared by nucleophilic cleavage of furan ring of [1]benzofuro[2,3‐__e__][1,2,4]triazine derivative **1**. Some of them were used for the preparation of derivatives of [1,2,4]triazolo[4,3‐__d__][1,2,4]triazine (**6a‐6d**) and tetr
