Trispyrazolylborate ligands (TpR), also known as scorpionates, have a long and rich history. The sterics and electronics of TpR can be tuned by varying the R substituents. Rhodium-scorpionate complexes catalyze the polymerization of acetylenes. More recent work from our laboratory has focused on anchoring variants of Tp catalysts on resin supports, in an effort to create recyclable heterogeneous catalysts. We will present our findings on the exploration of various mechanistic pathways of phenylacetylene polymerization by TpRh(cod) catalysts. Our results are also used to aid in the design and development of heterogeneous-supported catalysts with novel TpR analogues.
