Many of the initial, fundamental reaction discoveries in organometallic chemistry were made utilizing complexes of rhenium and were then commercialized with later, more traditionally reactive transition metals such as Rh, Ir, Pd, and Pt. In this presentation I will show that organometallic rhenium complexes supported by the tridentate, PCP (1,3-bis(dialkylphosphinomethyl)benzene) pincer ligand are capable of exhibiting new and unusual reactivity modes that not only challenge some of the rules we are taught as undergrads, but that there are still plenty of new reactions that rhenium can allow us to discover.
Topics to be discussed will include the formation of pincer-rhenium complexes, the dehydrogenation of aliphatic C-H bonds, cases where pKa values failed to predict reactivity, and the ability to disrupt the aromaticity in an unfunctionalized PCP-pincer for the first time.
