Visible Light Promoted Derivatizations of Helicenes.
Jakubec, Martin ; Storch, Jan ; Ghosh, I. ; König, B.
We developed new reductive and oxidative approaches to late-stage derivatization exploiting intrinsic photochemistry of helicenes with emphasis on the use of very simple and readily available bromo- and aminohelicenes.

Photochemical Derivatization of Helicenes.
Jakubec, Martin ; Ghosh, I. ; Storch, Jan ; König, B.
This work is focused on the use of simple helicene derivatives as substrates for modern photochemical methods. Halogen containing substrates are transformed in the reductive pathway to helicenyl radicals, before being trapped by different radical traps. In the oxidative pathway, activated alkoxyhelicenes undergo photoredox catalyzed reactions, yielding various carbon-carbon, as well as carbon-heteroatom containing compounds.\n
