Perfluoro-enolate chemistry: An 'electrophile-coexisting' procedure for carbon-carbon bond forming reactions with an ester lithium F-enolate
A novel 'electrophile-coexisting' procedure is developed for effecting aldol reactions and Michael additions with the lithium F-enolate of ethyl tetrafluoropropionate without appreciable occurrence of defluorination from the F-enolate.
