Application

Ethyltriphenylphosphonium iodide can be used as:
  • An efficient catalyst for N,N-dimethylation of primary aromatic amines with methyl alkyl carbonates.
  • A phase transfer catalyst for the synthesis of 3-hydroxyflavones from chalcones via Algar−Flynn−Oyamada synthesis.

Reactant involved in:
  • Synthesis of diarylmethine derivatives, phosphonium salts, and bismuth(III) polynuclear halide complexes
  • Asymmetric hydrogenation
