Metal Catalyzed

The distannyl-bridged poly bis(dimethylstannyl)ferrocene, 5, was synthesized through either the metal-catalyzed intermolecular dehydrogenative condensation of the bis(dimethylstannyl)ferrocene, 6, or the ring-opening polymerization of the distannane-bridged [2]ferrocenophane, 7. Both polymerization strategies yielded compounds displaying NMR (1H, 13C, 119Sn) evidence for a distannane bridged polymer. A modest moderate molecular weight (GPC; Mw = 9.5 × 104 Da, PDI = 1.76) was found for polymer 5 prepared by dehydrogenative condensation. Polymer 5 displayed electronic communication (≈ 0.2 V) between neighbouring iron centers, similar to those reported for monobridged ferrocenyl stannane polymers. Polymer 5 was further characterized by UV–vis spectroscopy, elemental analysis, and modeled with the related distannyl-8 and tristannyl-9 bisferrocenes using DFT at the SDD level of theory.

Preparation and characterization of a small library of symmetric trans-di(4-pyridyl)porphyrin dimers, obtained by either Glaser–Hay or Sonogashira coupling reactions from appropriately prepared trans-di-4-pyridylporphyrin precursors, is presented. The porphyrin dimers are differentiated by a phenyl-alkynyl bridge of increasing length at one meso-position, while for all the derivatives the two remaining opposite meso-positions are tailored with a phenyl moiety bearing a short polyether chain. Coordination of the four pyridyl groups with appropriate metal fragments may be exploited to construct tubular hollow structures, with varied internal sizes, depending on the choice of the porphyrin dimer component.

The synthesis and characterization of four metalloporphycenes containing a [MCp*]+ (Cp* = pentamethylcyclopentadiene; M = Rh , Ir , and Ru ) fragment directly bonded to the π-framework of the macrocycle were obtained. The electrochemical and optical properties of these complexes, studied in their respective free-base forms, revealed that the electron acceptor properties of the macrocycle can be enhanced by the coordination of an organometallic fragment to the π-electron face. In the case of the "fused" ruthenocene adduct, the corresponding nickel complex was also prepared. Here, less electronic communication between the ruthenocene moiety and the macrocycle was seen; however, the basic electron acceptor properties of the macrocycle were retained.
