摘要：
The synthesis of a new class of water-soluble osmium tetraphenylporphyrinates, complexes of the tetrakis(4-phosphono-methylphenyl)porphyrin anion [H-2(tP(4)O(8){OH}(4)mpp)](4-) (5), is described. Starting from OsCO(tmecpp)thf (2a) and OsO2(tmecpp) (1b), the new complexes 5a-c were synthesized by a four-step reaction with Os(t{OH}(4)mpp)LL' (2a-b), Os(tBr(4)mpp)LL' (3a-b), and Os(tP(4)O(4){OEt}(8)mpp)LL' (4a-c) as intermediates. The new complexes were characterized by UV/Vis, IR, H-1 NMR, and P-31 NMR spectroscopy, as well as by cyclic voltammetry and electrophoresis.
