Abstract

AbstractThe synergistic combination of three catalytic processes – photoredox, enamine and hydrogen atom transfer (HAT) catalysis – enabled the β‐isomerization of 2‐decalones towards the thermodynamically most stable trans‐isomers. A library of iridium (III) complexes and organic dyes were screened in combination with cyclic amines and thiols which after optimization gave the desired trans‐2‐decalones with high trans/cis ratios of 60 : 40 up to 98 : 2.
