  Preparation of Aza-Polycyclic Aromatic Compounds via Superelectrophilic Cyclizations

  摘要：

  [GRPHICS]Alkenyl-substituted N-heterocycles react in superacidic CF3SO3H (triflic acid) to produce dicationic intermediates. These superelectrophiles undergo cyclizations to give varied aza-polycyclic aromatic compounds in generally good yields (27-99%, 16 examples). Theoretical calculations indicate a preference for charge-separated dicationic intermediates.

  摘要：

  揭示了包含杂环胺化合物的配体、组合物和金属配体络合物，这些化合物在催化转化中非常有用，例如将单体聚合成聚合物。这些催化剂具有高性能特征，包括将共聚单体更多地并入乙烯/烯烃共聚物中，其中这些烯烃例如为1-辛烯、丙烯或苯乙烯。这些催化剂还可以聚合丙烯形成同向聚丙烯。

• Synthesis and evaluation of a scintillant-containing solid support for use in combinatorial chemistry
  作者：Bruce Clapham、Andrew J Sutherland

  DOI：10.1016/s0040-4039(00)00141-6

  日期：2000.3

  A scintillant monomer, 2,5-diphenyl-4-vinyloxazole, has been synthesised and co-polymerised with 4-ethylstyrene, divinylbenzene and 4-vinylbenzyl chloride in the presence of a toluene porogen, to form a scintillant-containing macroporous resin. Despite prolonged exposure to organic solvent, this resin retains the ability to scintillate efficiently in the presence of ionising radiation.

• Synthesis and scintillating efficiencies of 4-functionalised-2,5-diphenyloxazoles

  DOI：10.1016/s0040-4039(97)10435-x

  日期：1997.12

  A series of 4-functionalised-2,5-diphenyloxazoles has been synthesised. Each member of the series has been assessed for the ability to scintillate in the presence of ionising radiation. The scintillation counting efficiency of each member of the series has been determined relative to 2,5-diphenyloxazole, a widely used scintillant molecule. (C) 1997 Published by Elsevier Science Ltd.

  Ligands, compositions, and metal-ligand complexes that incorporate heterocycle-amine compounds are disclosed that are useful in the catalysis of transformations suchas the polymerization of monomers into polymers. The catalyst have high performance characteristics, including higher comonomer incorporation into ethylene/olefin copolymers, where such olefins are for example, 1-octene, propylene or styrene. The catalysts also polymerize propylene to form isotactic polypropylene.
