The main focus of the Stradiotto group has centered on the development and application of novel electronically rich, sterically encumbered P,N-based ancillary ligands for use in late metal catalysis, including Pd and Au chemistry. To this end, the Stradiotto group has developed the DalPhos series of ligands, of which Me-DalPhos (751413) and Mor-DalPhos (751618) in particular have led to considerable improvements in ubiquitous and/or challenging catalytic transformations, including the Buchwald-Hartwig Amination reaction and alkyne hydroamination. The DalPhos ligands not only engage classically difficult reaction partners (often at ambient temperature) but have also been applied successfully to a variety of synthetic challenges, such as the monoarylation of ammonia, hydrazine, and acetone. The Stradiotto group also established the applicability of the DalPhos ligand class in Au-catalyzed hydroamination chemistry involving challenging reaction pairings including the addition of secondary dialkylamines to internal alkynes.
