Organoamidometallics-III. 2,6-Dimethylpyridine and 1,4-dioxan as weakly coordinating polar solvents for decarboxylation syntheses of N,N-dimethyl-N′-(polyfluorophenyl)ethane-1,2-diaminato(1-)platinum(II) complexes

The complexes, Pt[N(p-HC₆F₄)CH₂CH₂NMe₂]X(L)(X = Cl, L = Ph₃P; X = I, L = pyrazine) have been prepared by reaction of PtX₂(dmen) (dmen = N,N-dimethylethane-1,2-diamine) with TlO₂CC₆F₄H-p, C₆F₅H and L in hot 2,6-dimethylpyridine (dmpy), and are considered to have L trans to -NMe₂. The pyrazine complex was also obtained in very low yield from an analogous synthesis in 1,4-dioxan. Reaction of PtBr₂ (dmen) with TlO₂CC₆F₄H-p and C₆F₅H in 2,6-dimethylpyridine without an added ligand gave a low yield of Pt[N(p-HC₆F₄)CH₂CH₂NMe₂](O₂CC₆F₄H-p)(dmpy).
