✦ Synopsis


Ab initio calculations at the B3LYP/6-31G* level on N-methoxy-N-dimethylaminoformamide and its rearrangement to methyl formate and 1,l-dimethyldiazene through the HERON reaction, have been carried out in conjunction with an experimental study of the HERON reactions of N,N'-diacyl-N,N'-dialkoxyhydrazines. Substituent effects are in accord with the theoretical properties of the transition state and point to an anomericaily driven process in which donor groups on the anomeric nitrogen and withdrawing groups on the migrating alkoxy oxygen facilitate the rearrangement process.

## Abstract The deprotonation of __N__‐allylbenzimidazolium halides **9a**–**d** initially results in the formation of the __N__‐allyldibenzotetraazafulvalenes **10**. These electron‐rich olefins rearrange to give 1,1′,2′,3′‐tetraalkyl‐1′,2′‐dihydro‐2,2′‐bibenzimidazoles **13**, either by a 3‐aza‐C
