Abstract

We report a rhodium-catalyzed anti-Markovnikov regioselective hydrosilylation of trifluoromethylalkenes with substituted silanes giving various α-trifluoromethyl-β-silanes in good to excellent yields. The hydrogenation products were obtained via the same key intermediate treated with methanol as a protic solvent. Both transformations had a broad functional tolerance and were expected to facilitate the construction of complex α-trifluoromethyl compounds.
