novel organic photoredox catalyst was discovered by simply adding a catalytic amount of TfOH as a co-catalyst to readily available thioxanthone. The new catalyst, 9-HTXTF, shows a sufficiently long singlet lifetime and adequately strong oxidation potential, as well as relatively facile photoexcitation, with applications in the hydrogenation and deuteration of carbonylated alkenes.
通过简单地将催化量的 TfOH 作为助催化剂添加到容易获得的噻吨酮中,发现了一种新型有机光氧化还原催化剂。新型催化剂9-HTXTF具有足够长的单线态寿命和足够强的氧化电位,以及相对容易的光激发,可用于羰基化烯烃的氢化和氘化。
