<sup>R</sup>PCP (1,3-Bis(dialyklphosphinomethyl)arene) ligated complexes are widely used in organometallic and organic catalysis for their stability under harsh conditions. Current synthetic methods for these ligands use expensive and hazardous starting materials, which make large-scale preparations challenging. We report a new synthesis for this ligand framework that allows for large-scale preparations and easy access to greater functionality. We have used this synthetic method to prepare <sup>Me4</sup>PCP and corresponding iridium complexes, and show that decreasing the steric profile of PCP changes the reactivity of the metal complexes compared to bulkier PCP ligands.
