Pincer ligand frameworks have become popular targets to study coordination and organometallic chemistry of transition metals. They are particularly advantageous due to the kinetic stability provided by chelation, as well as the mediation of open coordination sites about the metal. Our laboratory has been exploring the reactivity of a class of anionic pincer ligands built upon a central pyrrolyl unit. This ligand class (<sup>R</sup>PNP) has successfully stabilized a number of iron compounds in multiple oxidation states, spin states, and coordination spheres. This lecture will discuss the synthesis and reactivity of new iron compounds featuring the PNP ligand, and their application towards hydrosilylation catalysis. In particular, novel mechanisms involving the insertion of unsaturated substrates into iron heteroatom bonds will be highlighted.<br/>
