When running a Suzuki reaction between an alkyl boronic acid and aryl iodide in the presence of a palladium (0) catalyst, a student observes a lot of reduced aryl iodide instead of the desired product. By name or number, identify all of the following three changes which could reduce the amount of reduced aryl iodide formed: 1) Running the reaction with more equivalents of boronic acid 2) Running the reaction with more equivalents of aryl iodide 3) Switching to an aryl bromide over the aryl iodide
