Abstract

The palladium-catalysed cross-coupling reactions of arylboronic acids with a variety of π- 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.
