1H-Pyrazole, 1-(2-bromo-1,1,2,2-tetrafluoroethyl)-

Pyrazolyltetrafluorobromoethane is a fluoroalkylbromide that is a radical source of the pyrazolyl tetrafluoroethyl moiety. Alternatively, it can be also selectively metallated at the fluorinated carbon with Turbo Grignard reagent at low temperatures and the resulting thermally unstable anion can act as a nucleophilic fluoroalkylation reagent towards a wide variety of electrophiles, such as aldehydes, ketones or sulfonylimines.
