Resumen:
We have studied the Pd-catalyzed cross-coupling reaction of a stannane derived from selenium n-Bu3SnSePh (1) with aryl and perfuoroalkyl iodides. Herein a very eficient one-pot two-step selenylation reaction to form a CSe bond is reported. Ph2Se2 reacts with Na metal in liquid ammonia yielding PhSe_ ions. To this solution n-Bu3SnCl was added to afford 1, which was introduced in the palladium-catalyzed coupling reaction without isolation. These reactions afford functionalized diarylselenides and phenylperfuroalkyl selenides from good to high yields (3898%).
