## Abstract The radical anion of __trans__‐10b, 10c‐dihydropyrene (V), which is formed upon reduction of the isomeric [2.2]metacyclophane‐1,9‐diene (III) with solvated electrons, has been identified by its ESR.‐spectrum. The large coupling constant (19.1 Gauss), due to the two equivalent β‐protons
## Abstract The photoisomerization of __trans__‐10b,10c‐dimethyl‐10b,10c‐dihydropyrene (1), its 2,7‐di‐__tert__‐butyl derivative 5 and a series of potassium sulfonate derivatives of 1, in both [D~8~]1,4‐dioxane and [D~2~]dichloromethane as solvent, has been studied using λ = 420–570 nm irradiation.
