  Synthesis and photoactivated insecticidal activity of tetraethynylsilanes

  摘要：

  A series of tetraethynylsilanes (TETS) have been synthesized by reaction of silicon tetrachloride (SiCl(4)) with Ar-C CLi, which was prepared in situ by treatment of Ar-C CH with n-BuLi For these TETS thus prepared. their photoactivated insecticidal activities against the 4th-instar larvae of Aedes albapictus (Skuse) were evaluated to enrich the structure-activity relationship. In particular, compound 8 exhibited excellent photoactivated insecticidal activity, the LC(50) value was 0.1346 mg; L(-1) under UV light treatment and the irradiation-generated enhancement in the activity was more than 69 58-fold, thus could be exploitable as ideal analog candidates in the search for new photoactivated insecticide leads.

  Synthesis of conjugated 2 and 2,5-(ethenyl) and (ethynyl)phenylethynyl thiophenes: fluorescence properties

  摘要：

  Nano conjugated thienylethenyl and thienylethynyl Compounds with controlled Structure and dimensions have been efficiently prepared, by heterocoupling reaction between 1,4-(thienylethynylphenyl)phenylacetylene (or thienylethenyl)phenylacetylene and 2- or 2,5-dihalothiophene. Conjugated 1,4-di(2-thienylethynylphenyl)- (or 2-thienylethenylphenyl)-1,3-butadiyne were obtained by the homocoupling of the terminal acetylenes in excellent yield. The end-capped (N,N-dimethylaminophenyl)- and [3,5-di(trimethylsilylethynyl)-1-ethynyl]-2,5-di(iodo)thiophene were obtained by the heterocoupling between the corresponding terminal acetylene and 2,5-di(iodo)thiophene, catalyzed by the bis(triphenylphosphine)palladium and cuprous iodide system in excellent yield.

  Conjugated mono(arylethynyl)oligothiophene structures have been obtained starting with (E)-[1-(2'-thienyl)-2-(p-phenyl)]ethyne (E)-7 and 2-[p-(iodophenyl)ethynyl]thiophene 8. Conjugated nanostructures were synthesized by oxidative coupling between the terminal acetylenes (E)-7 and 8 to give, respectively, 1,4-di[(2-p-(iodophenyl)ethynyl)thienyl]-1,3-butadiyne and 1,4-di[(2-p-iodophenylethynyl)thienyl]-1,3-butadiyne. All the thiophene derivatives synthesized show an important fluorescence radiation emission, with a bathochromic shift, which increases with the conjugation of the chain. (C) 2004 Elsevier Ltd.
