Abstract: Electrochemical reductive silylation of trifluoromethylbenzene by the sacrificial anode technique selectively led, in a THF/DMPU mixture instead of THF/HMPA and according to the charge passed, to the corresponding mono-, bis-or tris-trimethylsilyl derivatives, respectively PhCF2TMS, PhCF (TMS) 2 and PhC (TMS) 3. This reaction, without any chemical equivalent, was extended to a molar scale synthesis, using a tubular flow ...
