Abstract
Manganese dioxide is employed as an in situ oxidant for the one-pot conversion of alcohols into imines. In combination with polymersupported cyanoborohydride (PSCBH), a one-pot oxidation-imine formation-reduction sequence is reported. This procedure enables alcohols to be converted directly into both secondary and tertiary amines.
