Easily Prepared Mono(N,N‐dialkylamino)phosphine Palladium(II) Complexes: Structural and Catalytic Evaluation

The search for efficient, active and universal catalyst systems for transition‐metal catalyzed cross‐coupling reactions, continues to be of interest to researchers world‐wide. Herein, we report two new Pd(II) complexes, effortlessly prepared from N,N‐dialkylamino‐phosphines for Suzuki‐Miyaura cross‐coupling reactions. These sufficiently hindered (% VBur=30.0–31.5 %) and electron rich (vCO=1947.41–1946.29 cm−1) aminophosphines formed active catalysts for Suzuki‐Miyaura coupling of aryl bromides and chlorides. New mono‐(N,N‐dialkylamino)phosphine based palladium (II) complexes were successfully prepared and their crystal structures determined. The complexes showed moderate to high catalytic performance in Suzuki‐Miyaura cross‐coupling of aryl‐bromides and chlorides which could be ascribed to their structural features.
