An Exceptional Hydroboration of Substituted Fluoroolefins Providing Tertiary Alcohols
摘要:
[GRAPHICS]A rare hydroboration-oxidation providing 3 degrees -alcohols has been achieved in the case of 1,1,2-perfluoroalkyl(MI)ethylenes. The hydroboration of substituted perfluoroalkyl(aryl)ethylenes with dichloroborane reveals that the regioselectivity does not entirely depend on the electronics of the fluoroolefins.

Addition of perfluorobutyl iodide to CC multiple bonds is efficiently achieved by sodiumdithioniteunder ultrasonic irradiation or phasetransferconditions. Perfluorobutyl substituted alkenes are obtained from the β-iodo-perfluoroalkanes resp.-alkenes by base-catalyzed elimination resp. reductive cleavage.
