Abstract
Isomerisation and dehydrogenation of 5‐hydroxy‐benz(ed)‐indoline (I) over a palladium catalyst have been studied systematically. In the absence of pre‐adsorbed hydrogen, dehydrogenation to 5‐keto‐1,5‐dihydro‐benz(ed)indole (IV) occurs. In the presence of hydrogen or a hydrogen donor such as tetraline, isomerisation to 5‐keto‐1,3,4,5‐tetrahydro‐benz(ed)indole (II) predominates.
