Enol acetate hydroboration
Abstract
The mechanism of enol acetate hydroboration has been studied by examination of the hydroboration–protonolysis of cyclohex-1-enyl acetate. It has been shown that in this case the initial hydroboration proceeds not by exclusive β-addition of the boron to the enol acetate double bond but by both α- and β-addition modes. The mechanism has been further investigated by using perdeuteriodiborane.
