potent organic pyrimidopteridine photoredox catalyst (E*[PrPPT*/PrPPT·–] = +2.10 V vs SCE in MeCN), the photo-mediated hydroamination of stilbenes was enabled using unprotected, primary aliphatic, allylic, benzylic amines for the synthesis of various α-phenyl phenethylamine derivatives. Notably, the stereogenic center of α-chiral amines was fully preserved. Both starting materials serve as competent quenching

I zinc we're alone now: The title reactions were achieved in an undivided cell fitted with a pair of zinc electrodes in aqueoussolution. A preliminary study on the relationship of reaction activity and surface morphology showed that the deposited zinc powders with nanoscale architectures had very high activity.
