A new palladium-catalyzed cross-coupling reaction between arylboronic acids and mixed anhydrides, generated in situ from carboxylic acids and pivalic anhydride, is presented. Optimization of the new catalyst and the reaction conditions led to the development of a convenient one-pot ketone synthesis directly from carboxylic and boronic acids in the presence of different (phosphane)palladium complexes
The invention provides bupropion analogue compounds capable of inhibiting the reuptake of one or more monoamines. The compounds may selectively bind to one or more monoamine transporters, including those for dopamine, norepinephrine, and serotonin. Such compounds may be used to treat conditions that are responsive to inhibition of the reuptake of monoamines, including addiction, depression, and obesity.

A new strategy for the synthesis of α-alkylated ketones from secondary alcohols and primary alkenyl alcohols via a tandemtransferhydrogenation/hydrogen autotransfer process was proposed and successfully accomplished. Mechanistic experiments supported that functional groups in bpy ligand are crucial for the transferhydrogenation and hydrogen autotransfer process. Furthermore, the utilization of the
