Trifluoromethylation of Ketones and Aldehydes with Bu3SnCF3
摘要:
The (trifluoromethyl)stannane reagent, Bu3SnCF3, was found to react under CsF activation with ketones and aldehydes to the corresponding trifluoromethylated stannane ether intermediates at room temperature in high yield. Only a mildly acidic extraction (aqueous NH4Cl) is required to release the corresponding trifluoromethyl alcohol products. The protocol is compatible with acid-sensitive functional groups.

The mechanism of the hydrostannation of strongly electrophilic carbonylcompounds has been studied. From the kinetics, and the solvent and substituenteffects, it appears that the addition reaction proceeds by nucleophilic attack of the hydride hydrogen on carbon. Further aspects of this and secondary reactions are discussed.
