Traditional iridium intermediate switches from allylic substitution to cross coupling when exposed to blue light
‘We grabbed a well-known iridium catalytic intermediate and unveiled a completely new application,’ says Paolo Melchiorre from the Institute of Chemical Research of Catalonia (ICIQ) in Spain. His team has revealed that under blue light a traditional allylic substitution catalyst completely switches reactivity to enable enantioselective cross couplings.
