Abstract
A dehydrogenative functionalization of styryl carbon-carbon double bonds with triflamide is described via dual visible-light photoredox/cobaloxime catalysis. A range of allylic triflamides (20 examples) were isolated in moderate to good yields (up to 88%) under stoichiometric acceptorless conditions. Dedicated labelling, as well as spectroscopic experiments, enabled to shed light on the concatenated photo- and chemo-catalytic cycles. (Figure presented.).File in questo prodotto:
