A small library of chiral imidate-ferrocenylphosphane ligands was efficiently synthesized (8 examples) and evaluated in the iridium(I)-catalyzed hydrogenation of unfunctionalized and poorly functionalized olefins. These catalysts perform very well in a range of examples (yields and ee's up to 100%).
Chiral imidate–phosphanes were developed as a new type of N,P ligands. These ligands are easily accessible through a one‐step procedure starting from a commercially available chiral aminophosphane and an imidate precursor. Excellent performance of the catalyst system was observed with various carbon nucleophiles in the Pd0‐catalyzed asymmetric allylic alkylation (up to 99 % yield and >99 % ee). Moreover, good to excellent enantioselectivities could also be obtained in the allylic alkylation of more difficult linear unhindered substrates and cyclic substrates, demonstrating that this new catalyst system has a broad substrate scope.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
