Direct Acylation of Aryl Bromides with Aldehydes by Palladium Catalysis
摘要:
A new protocol for the direct acylation of aryl bromides with aldehydes is established. It appears to involve palladium-amine cooperative catalysis, affording synthetically important alkyl aryl ketones in moderate to excellent yields in a straightforward 7 manner, and broadening the scope of metal-catalyzed coupling reactions,

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
