Abstract

This Account documents our recent progress toward the application of new P,N-ligands in transition-metal catalysis, including Ir-catalyzed ketone transfer hydrogenation, Pd-catalyzed cross-coupling of N-H containing substrates as well as acetone with aryl halides, and Au-catalyzed hydroamination of alkynes with dialkylamines.

1 Introduction

3 Pd-Catalyzed C-N Cross-Coupling and Acetone α-Arylation

3.1 Development of a Highly Versatile Catalyst System

3.2 Ammonia Monoarylation

3.3 Hydrazine Monoarylation

3.4 Acetone Monoarylation

4 Au-Catalyzed Hydroamination of Dialkylamines and Alkynes

5 Summary and Conclusions

Key words

cross-coupling - homogeneous catalysis - hydrogen transfer - palladium - amines
