The cross-coupling of arylboronic acids with a variety of π-deficient heteroaryl chlorides has been shown to occur in high yield in the presence of [1,4-bis-(diphenylphosphine)butane]palladium(II) dichloride as catalyst.

The palladium-catalysed cross-coupling reactions of arylboronic acids with a variety of pi-deficient heteroaryl chlorides proceed in high yield. [1,4-Bis(diphenylphosphino)butane]palladium(II) dichloride was found to be a very satisfactory catalyst for monocyclic heteroaryl chlorides, whereas tetrakis(triphenylphosphine)palladium(O) was found to be excellent for a range of chloroquinoline derivatives.
