catalyst 1 with the "green" oxidant 35% hydrogenperoxide displays high activity and complete substrate selectivity in the epoxidation of terminalalkenes because of stringent steric and electronic requirements. In the presence of isolated dienes bearing terminal and internal double bonds, epoxidation is completely regioselective toward the production of terminal epoxides. Insight into the mechanism is
