  Synthesis and Characterization of Mixed Oligoheterocycles Based on End-capped Oligothiophenes

  摘要：

  A homologous series of mixed oligoheterocycles 2-6, based on the end-capped quinquethiophene EC5T 1, was synthesized by the introduction of electronegative heteroatoms, such as oxygen and nitrogen, into the conjugated Jc-system. This led to novel structures in which the central thiophene unit of the parent compound 1 is substituted by other heterocycles (thiazole, 1,3,4-thiadiazole, furan, oxazole, Id,4-oxadiazole) that have a more pronounced acceptor character. The characterization of the optical and electrochemical properties clearly reveal the influence of the heteroatoms on the electronic properties. The electron-withdrawing character of the central heterocycles renders the oxidation of the oligomer more difficult while reduction is facilitated. Moreover, in some cases a hypsochromic shift of the longest-wavelength absorption and emission is observed along with a significant enhancement of the fluorescence quantum yield in solution and in the solid state. The HOMO/LUMO energy difference, determined from optical and electrochemical measurements, corresponds qualitatively well with the values obtained from semiempirical calculations. An X-ray structural determination was performed on oligoheterocycle 6 and the experimental and calculated data are compared.

• Synthesis of 1,4-keto esters and 1,4-diketones via palladium-catalyzed acylation of siloxycyclopropanes. Synthetic and mechanistic studies

  The reaction of a variety of siloxycyclopropanes with acid chlorides in the presence of a catalytic amount of a palladium/phosphine complex gives 1,4-dicarbonyl compounds to good yield. 1-Alkoxy-1-(trialkylsiloxy)-cyclopropanes react with both aromatic and aliphatic acid chlorides in chloroform to give 1,4-keto esters. Synthesis of 1,4-diketones by the acylation of 1-alkyl- or 1-aryl-1-siloxycyclopropanes has been achieved by carrying out the reaction if HMPA under 10-20 atm of carbon monoxide. Kinetics studies and product analysis revealed the unique mechanism of this reaction, which involves rate-determining cleavage of the strained cyclopropane carbon-carbon bond with a coordinatively unsaturated acylpalladium chloride complex. Ab initio calculations of hydroxylated cyclopropane model compounds showed that the unique reactivities of the siloxycyclopropanes may be correlated with the molecular orbital properties of these compounds rather than their ground-state structural properties.
