The trifluoromethyl anion rapidly decomposes into difluorocarbene (:CF2) and fluorine ion, limiting its applicability in synthesis. Here, the authors report a strategy to generate and use the short-lived CF3- intermediate from stable CF3H gas via fast biphasic mixing in precisely customized flow dissolvers.
