products reliably under all reaction conditions. Compound 5 did not provide cross coupled products under any of the reaction conditions used. The Negishi reaction was the only one that worked for templates 4 and 11. Studies indicate that oxidative addition of the most reactive carbon–halogenbond to Pd(0) is followed by elimination of the second halide, when the second halide is a bromide or an iodide
