1. A New Twist on Pincer Complexes for Catalysis John Protasiewicz, Department of Chemistry Case Western Reserve University, Cleveland, Ohio 44106
High twist angle pincer complexes: We have shown that a variety of such complexes can be quickly made, are very air and water stable, and that they are also structurally rigid and sterically demanding.
