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.
三种催化过程的协同组合——光氧化还原、烯胺和氢原子转移 (HAT) 催化——使 2-decalones 的 β-异构化成为热力学上最稳定的反式异构体。结合环状胺和
