Resumo

The stabilizing effects and bonding properties of the Pd metallic center in {[}(K-2-P,N-Mor-Dalphos)Pd(Ar) Cl] complexes and related NH3 adducts were investigated by density functional theory (DFT), the intrinsic bond orbital (IBO) approach and the Su-Li energy decomposition method (Su-Li EDA). The IBO analysis showed that the P atom from the P,N-Mor-Dalphos structure has stabilizing contributions in all Pd-Cl and Pd-NH3 bonds in the complexes. According to the Su-Li energy decomposition analysis, the main energy that drives the interaction between the {[}Mor-Dalphos-Pd(Ar)] moiety and Cl- is the electrostatic term, therefore, the electrostatic energy interaction between them might be an important factor for taking into account when designing other {[}Mor-Dalphos-Pd(Ar)]-Cl precatalysts.
