CAS 5717-37-3: (Carbethoxyethylidene)triphenylphosphorane

Description:(Carbethoxyethylidene)triphenylphosphorane, with the CAS number 5717-37-3, is a chemical compound that belongs to the class of phosphoranes, which are characterized by the presence of a phosphorus atom bonded to three phenyl groups and a carbethoxyethylidene moiety. This compound typically exhibits a high degree of stability due to the resonance stabilization provided by the phenyl groups. It is often used as a reagent in organic synthesis, particularly in the formation of alkenes through the Wittig reaction, where it acts as a phosphonium ylide. The presence of the carbethoxy group enhances its reactivity and solubility in organic solvents. Additionally, the compound may display interesting optical properties due to the conjugated system formed by the ethylidene and phenyl groups. Its applications extend to various fields, including medicinal chemistry and materials science, where it can be utilized in the synthesis of complex organic molecules. Safety data should be consulted for handling and storage, as with all chemical substances.
