Methyltriphenylphosphonium bromide

Application Summary：Methyltriphenylphosphonium bromide serves as a Wittig reagent for the preparation of linear olefins and the extension of unsaturated carbon chains. As a precursor to Wittig ylides, it is widely employed in the synthesis of unsaturated bonds in liquid crystal materials. It also finds extensive applications in organic synthesis and acts as an effective cationic phase-transfer catalyst.
