This account summarizes our recent progress on the copper-catalyzed direct introduction
of functionalized difluoromethylated building blocks, and more particularly, the CF2CO2Et motif. We also discuss how this work led us to develop new copper-mediated methodologies
to introduce the CF2PO(OR)2 motif, a valuable phosphate bioisostere.
Key words
fluorine - copper - difluoromethylene - phosphate mimic - C–H bond functionalization
