P. Pitre, Christopher D. McTiernan, Juan C. ScaianoOrganic dyes can be excellent catalysts
for photoredox chemistry,
offering low price, low toxicity, and an exceptional range of available
materials. Their use has been limited because in comparison to their
transition-metal catalysts the spectroscopic, kinetic, and electrochemical
information available is far more limited. To remediate this situation,
we have determined the necessary data for 14 readily available dyes
with excellent potential as photoredox catalysts. We have also demonstrated
the utility of these dyes through visible-light-mediated reductive
dehalogenation and Aza-Henry reactions. We envision that this collection
of data will lead to an increase in the use of cationic dyes in photoredox
processes because users will find the necessary information readily
available.
