  • Introduction of alkyl substituents to aromatic compounds
    Patent number: 10351492
    Abstract: Novel selective synthesis route to introduce primary alkyl groups on aromatic compounds is disclosed. The synthesis route is based on electrophilic aromatic substitutions of thionium ion species that are generated in-situ from aldehydes and thiols, affording benzyl sulfide that can be reduced with triethylsilane.

  • Polycyclic compounds, termed calixurenes, and uses thereof
    Patent number: 8962605
    Abstract: Disclosed is a novel family of macrocyclic compounds, coined calixurenes, which comprises linear and cyclic oligomers composed of alternating moieties of an aromatic unit and a ureatic unit, linked to one another via a bridging moiety. The disclosed calixurenes feature multiple heteroatom-containing groups, and can be designed so as to feature other functionalities, and can thus be used in a variety of applications. Further disclosed are processes of preparing the calixurenes, articles containing same and uses thereof.
