  • Publication number: 20140221655
    Abstract: The invention provides methods for substituting polyaromatic hydrocarbons or polyheterocyclic compounds with perfluoroalkyl groups. The methods can include heating a polyaromatic hydrocarbon substrate or a polyheterocyclic compound substrate in the presence of a perfluoroalkyl iodide, typically in a closed system, wherein the heating is sufficient to bring both the polyaromatic hydrocarbons or polyheterocyclic compound, and the perfluoroalkyl iodide, into the gas phase, thereby allowing the substrate to react with the perfluoroalkyl iodide in the gas phase to form polyaromatic hydrocarbons or polyheterocyclic compounds having one or more perfluoroalkyl substituents. The methods allow for the creation of versatile libraries of novel perfluoroalkyl-containing derivatives that can serve as important building blocks and active components in biomedical, electronic, and materials applications.

  • Patent number: 8586810
    Abstract: The present invention proposes a chiral diene ligand, a fabrication method thereof and applications thereof. The chiral diene ligand is a bicyclo[2.2.1] diene ligand having structural specificity and high stability, which favors the bicyclo[2.2.1] diene ligand to take part in asymmetric transformations, particularly an asymmetric addition reaction involving a metal catalyst in a basic environment. Most of the products of the reactions implemented by the chiral diene ligands of the present invention have superior optical activity. The method of the present invention comprises a first oxidation step, a saponification step, a second oxidation step, a deprotonation step, and a cross-coupling step. The chiral diene ligand of the present invention is very suitable to be used in the fabrication or synthesis of various chemicals and medical products.
