A new precatalyst for the Suzuki reaction - a pyridyl-bridged dinuclear palladium complex as a source of mono-ligated palladium(0)

A dinuclear pyridyl-bridged palladium complex, trans-(P,N)-[PdBr(mu-C5H4N-C-2,N)(PPh3)](2) 1, was obtained from material isolated from the Suzuki cross-coupling reaction of 2-bromopyridine with 2,4-diflorophenylboronic acid in the presence of catalytic (PPh3)(4)Pd. Complex 1 is an effective precatal...

More Information
Summary:A dinuclear pyridyl-bridged palladium complex, trans-(P,N)-[PdBr(mu-C5H4N-C-2,N)(PPh3)](2) 1, was obtained from material isolated from the Suzuki cross-coupling reaction of 2-bromopyridine with 2,4-diflorophenylboronic acid in the presence of catalytic (PPh3)(4)Pd. Complex 1 is an effective precatalyst for the Suzuki cross-coupling reactions of a variety organoboronic acids and aryl bromides, and represents a useful source of mono-ligated palladium(0), "(Ph3P)Pd(0)''.
