Pd, Pt, and Ru complexes of a pincer bis(amino)amide ligand

Rosario Scopelliti, Xile Hu, Oleg Vechorkin, Peng Ren, Isuf Salihu

An improved synthesis of pincer ligand bis[(2-dimethylamino)phenyl]amine (MeN2NH) was reported. Reaction of the Li complex of MeN2N with suitable Pd, Pt, and Ru precursors gave the corresponding metal complexes. The structures of the Pd, Pt, and Ru complex ...
