Abstract
Addition of perfluoro-tert-butyl alcohol to a toluene solution of alkene and cyclopropyl malonoyl peroxide increases the rate of dihydroxylation product formation and the stereoselectivity observed, providing a simple and effective method for acceleration of this important class of reaction. Basic hydrolysis of the crude reaction mixture provides access to syn-diols in high yield and stereoselectivity.
