A Multiligand Based Pd Catalyst for C−N Cross-Coupling Reactions
摘要:
An alternative approach to catalyst development, which led to a Pd catalyst based on two biarylphosphine ligands for C-N cross-coupling reactions, is reported. By effectively being able to take the form of multiple catalysts this system manifests the best properties that catalysts based on either of the two ligands exhibit separately and displays the highest reactivity and substrate scope of any system that has been reported to date for these reactions.

Abstract Addition of polyfunctionalized aryl, heteroaryl, and tertiary alkylmagnesium reagents to tertiary nitroalkanes at 25 °C in tetrahydrofuran produces, after reductive workup with FeCl2 and NaBH4 in ethanol, the corresponding polyfunctional secondaryamines in high yields.
