The use of highly active manganese (Mn)*, prepared by the Rieke method, was investigated for the direct preparation of benzylic manganese reagents. The oxidative addition of the highly active manganese to benzylic halides was easily completed under mild conditions. Moreover, benzylic manganese sulfonates and phosphates were prepared by direct oxidative addition of Mn* to the carbon–oxygen bonds of

A newsynthetic route to organomanganese sulfonate reagents has been developed. These useful reagents can be readily prepared via direct oxidative addition of highly reactive manganese to carbonoxygen bonds of the corresponding tosylates and mesylates under mild conditions.

in the ligand are crucial for the activity of catalyst and selective transfer hydrogenation is the determining step of the formation of alkenyl ketones as products. Notably, the present research exhibited also the unique potential of metal–ligand bifunctional catalysts for the activation of unsaturated alcohols as electrophiles for hydrogen auto-transfer process.
