Methyl(triphenyl)phosphonium iodide

Reactant for synthesis of Triphenylamine-based dyes and polyolefinic aromatic molecules with pyrene for use in dye-sensitized solar cells Diastereoisomeric carba analogs of glycal-derived vinyl epoxides for the production of carbasugars Alkaloid natural products via organocascade catalysis Triplet carbenes via oxidation of allene compounds Stilbenes via dehydrohalogenation-Heck olefination and Wittig-Heck reactions

(Methyl)triphenylphosphonium Iodide is the precursor to a wittig reagent.
