1-bromo-4-iodobenzene, (2 to 8 mol%) palladium acetate, acetonitrile, (0.22 g, 2.2 mmol, 4.4 equivalents) of triethylamine, and (0.11 g, 1.5 mmol, 3.0 equivalents) of acrylic acid were combined. What would happen if too much triethyamine was added to the reaction? Also if you added too much acrylic acid?
