Palladium pincer-complex-catalyzed selenylation of propargyl-, allyl-, benzyl-, and benzoyl halides could be achieved under mild reaction conditions employing trimethylstannylphenylselenide as selenylating agent. This reaction has a high functional group tolerance as carbmethoxy, tosylamino, nitro, aryl bromide, and unprotected hydroxy groups are tolerated. Mechanistic studies indicate that the catalytic
