CAS 1439-36-7: 1-(Triphenylphosphoranylidene)-2-propanone

Description: 1-(Triphenylphosphoranylidene)-2-propanone, also known as a phosphoranylidene compound, is characterized by its unique structure that features a triphenylphosphine moiety attached to a ketone. This compound typically exhibits a high degree of stability due to the resonance stabilization provided by the triphenylphosphine group. It is often utilized in organic synthesis, particularly in reactions involving carbonyl compounds, where it can act as a nucleophile or a catalyst. The presence of the phosphoranylidene group enhances its reactivity, allowing it to participate in various chemical transformations, including Wittig reactions and other coupling reactions. In terms of physical properties, it is generally a solid at room temperature and may exhibit moderate solubility in organic solvents. Its applications extend to the fields of organic chemistry and materials science, where it can be used in the development of novel compounds and materials. Safety data should be consulted for handling and storage, as with any chemical substance.
