Methyltriphenylphosphonium iodide Usage And Synthesis

Chemical Properties

WHITE TO LIGHT YELLOW POWDER

Uses

suzuki reaction

Uses

Methyltriphenylphosphonium iodide is as a reactant for synthesis of triphenylamine-based dyes and polyolefinic aromatic molecules with pyrene for use in dye-sensitized solar cells. Used as ligand in coupling reaction. It is also used as a precursor to a Wittig reagent.

Preparation

Methyltriphenylphosphonium iodide was prepared by the following procedure. Triphenylphosphine was recrystallized from ethanol and dried over phosphorus pentoxide under reduced pressure for 12 hr. A solution of 39 g (0.15 mol) of triphenylphosphine and 10.0 mL (22.8 g, 0.16 mol) of iodomethane in 105 mL of benzene was allowed to stir at room temperature for 12 hr. The precipitate was filtered, washed with benzene, and dried over phosphorus pentoxide under reduced pressure for 12 hr. The yield was 57 g (94%), mp 189°C (lit.2 mp 182°C).
