The direct halo-oxygenation of alkenes by IBX in the presence of potassium halide
is described, in which two issues have been approached: (a) the products are formed
atom-economically with retention of the main skeleton of IBX; and (b) the products
contain multi-functional groups offering further synthetic applicability.
