Oxidative Cross-Coupling of Boron and Antimony Nucleophiles via Palladium(I)

The use of an isolatable, monomeric Pd­(I) complex as a catalyst for the oxidative cross-coupling of aryl-antimony and aryl-boron nucleophiles is reported. This reaction tolerates a wide variety of substrates, with >20:1 selectivity for cross-coupled products. This strategy offers a new approach to achieving the selective cross-coupling of nucleophiles.
