Synthesis and Structural Characterization of a Fluorinated α-Diimine Platinum(II) Complex
摘要:
The preparation of an electron-deficient (N-N)PtCl2 complex in which the diimine C is substituted by CF3 is described. Thus, reactions between the diimine ligand 1 (R = CF3, R' = 2,6-dimethylphenyl) and PtCl2 (thermal reaction) or KPtCl3(C2H4) (photochemically activated) furnishes the corresponding (N-N)PtCl2 complex 2. The ligand 1 and its Pt complexes 2, as well as related (N-N)PtCl2 complexes 3 (R = CO2CD3, R' = 2,6-dimethylphenyl; a methanolysis product) and 4 (R = H, R' = 2,6-dimethylphenyl) have been characterized by X-ray crystallography.
