CAS 1099-45-2

Ethyl triphenylphosphoranylideneacetate

Description:

Ethyl triphenylphosphoranylideneacetate, with the CAS number 1099-45-2, is an organophosphorus compound characterized by its unique structure, which includes a phosphoranylidene group attached to an ethyl acetate moiety. This compound typically appears as a solid or viscous liquid and is known for its role as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds. It exhibits moderate stability under standard conditions but may decompose under extreme heat or in the presence of strong acids or bases. Ethyl triphenylphosphoranylideneacetate is often utilized in the Wittig reaction, where it acts as a phosphonium ylide, facilitating the conversion of carbonyl compounds into alkenes. Its reactivity is influenced by the electron-donating properties of the triphenylphosphine group, which enhances its nucleophilicity. Safety data indicates that it should be handled with care, as it may pose health risks if ingested or inhaled, necessitating appropriate safety measures during use.

(Carbethoxymethylene)triphenylphosphorane

CAS: 1099-45-2

(Carbethoxymethylene)triphenylphosphorane is a pharmacological treatment that has a water-vapor reaction mechanism. It inhibits the replication of DNA by binding to the nitrogen atom in fatty acid, forming a heterocyclic compound with a hydroxyl group, which prevents the formation of ATP. This drug also binds to monoamine neurotransmitters and light emission. (Carbethoxymethylene)triphenylphosphorane is used to treat patients with Parkinson's disease, Alzheimer's disease, and other neurodegenerative diseases.
