Hazard Note Irritant
Ethyl (Triphenylphosphoranylidene)acetate (synonyms: (Carbethoxymethylene)triphenylphosphorane) (CAS: 1099-45-2) , the primary application of this product lies in the Wittig reaction. This reaction allows the formation of carbon-carbon double bonds between an aldehyde or ketone and a carbonyl compound. The reaction involves the ylide form of the reagent, which reacts with the carbonyl carbon of the other molecule, forming a new double bond and releasing triphenylphosphine oxide as a byproduct.
This reaction is widely employed in the synthesis of various organic molecules, including:
Natural Products: The Wittig reaction has been instrumental in the synthesis of numerous natural products, such as complex carbohydrates, alkaloids, and terpenoids.
Pharmaceuticals: The reaction plays a crucial role in the development of new drugs by enabling the construction of specific carbon-carbon double bond frameworks within the target molecules.
Functional Materials: The Wittig reaction is also used in the synthesis of functional materials, such as polymers and organic semiconductors, where controlled placement of double bonds is essential for desired properties.
