We've already got blue light Suzukis and and conjugate additions, and reductive couplings and Buchwalds and ... yadda yadda yadda, but you know what haven't got yet? A photoredox version of the Nozaki Kishi Hiyama - and two smart groups figured out that would be a smart thing to do and came to a solution at just about the same time. I'll let you decide who did it better.
This one published yesterday.
My only comment on this one is really you couldn't have tried it with 4CzIPN (PC1 is the monocyano version of that)? I mean nobody wants to make the catalyst and I can't find anybody who currently sells 1469700-24-0.
And this is the other one that published today. L3 is this, and HE is the Hantszch ester. Kessil currently has a 390 and 427... both would likely work with this reaction in the Lighning.
As an author of the first work, I can reply to the comment concerning the photosensitizer. It's a matter of redox potentials, as well explained in the paper: those of 4CzIPN (we tried it in some preliminary tests we didn't mention in the paper) are unsuited for the reaction to occur. Moreover, we synthesize all the cyanoarene-type photosensitizers because the starting materials are rather inexpensive, and all the syntheses can be performed in a one-pot fashion. Btw, I found a supplier for 5CzBN, but 984€/g are definitely too much, its synthesis in the lab is undoubtedly cheaper, even for larger quantities. The same supplier sells also 4CzIPN (824€/g), and even in this case its lab synthesis is by far less…
