An exceptional hydroboration of substituted fluoroolefins providing tertiary alcohols.
[reaction--see text] A rare hydroboration-oxidation providing tertiary-alcohols has been achieved in the case of 1,1,2-perfluoroalkyl(aryl)ethylenes. The hydroboration of substituted perfluoroalkyl(aryl)ethylenes with dichloroborane reveals that the regioselectivity does not entirely depend on the electronics of the fluoroolefins.
