Application

Reactant for:
  • Preparation of building blocks for synthesis of fluoroallylic compounds
  • Synthesis of alcohols via hydrolysis of alkyl silyl ethers at neutral pH in buffered mixed organic-aqueous solutions
  • Nucleophilic fluorination of alkynyliodonium salts to form fluorovinylic compounds
  • Nucleophilic aromatic substitution (SNAr) reactions
Used in the successful synthesis of a single-crystal Dion-Jacobson phase, CsLaTa2O7, that has applications in photocatalysis and superconductivity.
