Abstract

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 (% V_Bur=30.0–31.5 %) and electron rich (v_CO=1947.41–1946.29 cm⁻¹) aminophosphines formed active catalysts for Suzuki-Miyaura coupling of aryl bromides and chlorides.
