  • Publication number: 20220250032
    Abstract: The invention relates to strong hydrogen-bond acidic sorbents. The sorbents may be provided in a form that limits or eliminates intramolecular bonding of the hydrogen-bond acidic site between neighboring sorbent molecules, for example, by providing steric groups adjacent to the hydrogen-bond acidic site. The hydrogen bond site may be a phenolic structure based on a bisphenol architecture. The sorbents of the invention may be used in methods for trapping or detecting hazardous chemicals or explosives.

  • Publication number: 20170029453
    Abstract: An organometallic complex of a tridentate bis(phosphine)-carbodicarbene ligand and a transition metal, is described. In some embodiments the ligand has the structure of Formula (I): The complexes are useful in methods of making an allylic amine carried out by reacting a 1,3-diene with a substituted amine in the presence of such an organometallic complex to produce by intermolecular hydroamination the allylic amine.
