Abstract
cis-Dihydroxylation of olefins with a catalytic amount of osmium tetroxide and N-methylmorpholine N-oxide proceeds smoothly in an organic solvent in the presence of dihydroxyphenylborane to give the corresponding phenylboronic esters in good yields. The use of a diol captor prevents further oxidation of the products and makes the isolation procedure easier.
