Abstract

We have studied the Pd-catalyzed cross-coupling reaction of a stannane derived from selenium n-Bu3SnSePh (1) with aryl and perfluoroalkyl iodides. Herein a very efficient one- pot two-step selenylation reaction to form a C–Se 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 ...
