## Abstract The pyrolysis of 1‐aroylamino‐4,5‐diphenyl‐1,2,3‐triazoles 1 yields, pressumably __via__ the 4,5‐diphenyl‐1,2,3‐triazolyl radical (2a), 2,3‐diphenyl‐2__H__‐azirine (11a) and 2‐aryl‐4,5‐diphenylimidazoles 14 as the major products. Upon irradiation 1‐benzoylamino‐4,5‐diphenyl‐1,2,3‐triazo
The regioselectivity of the intramolecular [2 +2] photocycloadditions of 1-AcyC3-oxa-1,5-hexadienes appears, in general, to follow "rule of five" closure and give annelated 2-oxa-bicyclo[2.1 .l]hexanes.
## Abstract Reaction of the 3,5‐diaryl‐1,2‐dithiolium salts 2 with the metal cyclopentadienides 4 and 9 leads to the formation of the tricyclic compounds 6 and 10 via a ring‐opened intermediate, which undergoes an intramolecular Diels‐Alder cyclization. Compounds 6 and 10 rearrange by treatment wit
