Tetramethylphosphonium iodide, with the CAS number 993-11-3, is a quaternary ammonium salt characterized by its phosphonium cation, which consists of a phosphorus atom bonded to four methyl groups and an iodide anion. This compound is typically a white crystalline solid that is soluble in polar solvents such as water and alcohols. It exhibits properties typical of quaternary ammonium salts, including high thermal stability and the ability to act as a phase transfer catalyst in organic reactions. Tetramethylphosphonium iodide is often used in organic synthesis, particularly in reactions involving nucleophilic substitutions and as a reagent in the preparation of phosphonium ylides. Its ionic nature contributes to its effectiveness in facilitating the transfer of reactants between different phases in heterogeneous reactions. Additionally, it is important to handle this compound with care, as it can be toxic and may pose environmental hazards if not disposed of properly.
