Olaf Tjabben
In this work, a mild NaBArF-mediated electrophilic trifluoromethylation of nonactivated silyl enol ethers is reported, using an Umemoto-type chloride salt thanks to a reactivity-modulation through its counter-anion. Hence, the key to succes...
Synthesis of New Fluoroboronated Materials by Chemical Modification of Fluorinated Functional Polymers [0.03%]
