The title compound, also known as 7-iodotropolone, C~7~H~5~IO~2~, exists in the crystalline state as the 2-hydroxy-7-iodocyclohepta-2,4,6-trien-1-one tautomer and not as 2-hydroxy-3-iodocyclohepta-2,4,6-trien-1-one. There is a bifurcated O—H...O bond with two acceptor O atoms. One of these acceptors

The title compound, also known as 2-amino-5-[4-(octylamino)phenyl]tropone, C 21 H 28 N 2 O, contains two crystallographically independent molecules in the asymmetric unit. The NH 2 group of the 2-aminotropone unit and the NH group of the aminobenzene unit participate in intermolecular hydrogen bondi

## Abstract 2‐(__tert__‐Butyl)‐3,7‐dehydrotropone (7‐(__tert__‐butyl)bicyclo[3.2.0]hepta‐1(7),2,4‐trien‐6‐one; **1**) was found to dimerize reversibly to **2A** by [2 + 4]‐cycloaddition/cycloreversion reaction. The equilibrium lies on the side of the highly strained dimer **2A** in the solid state,
