Abstract:
In the present work, we report the fabrication of a highly versatile ruthenium-based magnetically recoverable photoredox nanocatalyst with a large surface area. This visible light harvesting nanocatalyst was effectively used for cross-dehydrogenative coupling via C-H activation between tertiary amines and various carbon nucleophiles with high regioselectivity to afford the C-C coupled products in good to excellent yield using air as an oxidant under ambient conditions. The Ru-based catalyst was found to be a potential candidate from economical and environmental perspectives due to its magnetic recoverability and reusability.
