Abstrakt:	A convenient and effective method of palladium‐catalyzed C−H selenylation of the 2‐aryl acetamides assisted with removable 8‐aminoquinoline with readily available diselenides and selenyl chlorides has been developed. This selenylation reaction is scalable and tolerates a wide range of functional groups, providing a straightforward way of the preparing unsymmetrical diaryl selenides and dibenzoselene‐pinone. Preliminary mechanistic studies indicated that a single‐electron transfer type mechanism and facile C−H metalation are operative. [ABSTRACT FROM AUTHOR]
