A novel one-pot method for the synthesis of substituted μ-oxo-bis [tetraphenyl porphyrinatoiron] compounds ([TRPPFe]2O) from pyrrole and aromatic aldehydes was proposed and investigated in this paper. Four kinds of [TRPPFe]2O were designed and synthesized by one-pot reaction and characterized by elemental analysis, infrared spectra and ultraviolet-visible spectroscopy. Moreover, the [TRPPFe]2O yields of 18.7~22.4% could be obtained with this novel method under the optimum reaction conditions.

ABSTRACTThe synthesis and characterization of a 1,1′-binaphthyl based main chain chiral conjugated polymer, R-9, is described. The polymer is prepared from the palladium-catalyzed Suzuki coupling of an optically active binaphthyl molecule, (R)-2,2′-dihexyloxy-1,1′-binaphthyl-6,6′- diboronic acid, R-4 with 1,4-bis(p-bromostyryl)benzene (E:Z = 1:1.2), 8. The Suzuki coupling of 8 with 6-neopentyloxynaphthyl-2-boronic acid, 1 1, leads to the formation of a conjugated molecule 10. The structure of this molecule represents the repeat unit of R-9. The electronic absorption spectrum of 10 demonstrates that the degree of conjugation in the chiral conjugated polymer is almost the same as that of its repeat unit.
