Cyanomethylenetributylphosphorane (Cat No.: M091658) is a phosphorus ylide compound commonly used in organic synthesis, particularly in the Wittig reaction to form α,β-unsaturated nitriles. It features a nucleophilic ylide center stabilized by a cyano group and three butyl groups bonded to the phosphorus atom. This yellow to orange liquid is highly reactive with aldehydes and ketones, providing a valuable route to functionalized alkenes. Its electron-withdrawing cyano group enhances ylide stability and selectivity, making it a useful reagent in the synthesis of fine chemicals and pharmaceuticals.
