To a flame dried 20-mL microwave vial equipped with a magnetic stir bar was added Pd(dppf)Cl2 (9.8 mg, 0.014 mmol, 10 mol %). The vial was sealed with a Teflon microwave cap, and then evacuated and backfilled with nitrogen three times using a dual manifold Schlenk line. To the reaction mixture was added a degassed solution of iodide SI-3 (50.0 mg, 0.14 mmol, 1.0 equiv) in 1,4-dioxane (0.28 mL, 0.5M, degassed by freeze-pump-thaw) and Sn2(n-Bu)6 (97.4 mg, 0.17 mmol, 1.2 equiv). The reaction vessel was then moved to an oil bath, which was then heated to 100 °C.
