Applications
(Acetylmethylene)triphenylphosphorane is used as a Wittig reagent in synthetic chemistry, especially for the synthesis of functionalized pyrrolidines and cyclobutanones. It plays as a vital role in asymmetric allylboration for enantioselective synthesis of (+)-awajanomycin.It is also employed as a reactant in the preparation of 1,2-dioxanes with antitrypanosomal activity. Further, it is used in the preparation of amphibian pyrrolizidine alkaloids through allylic aminations and silicon-containing acyclic dienone musk odorants. In addition to this, it is involved in Domino Suzuki/Heck coupling reactions to prepare fluorenylidenes.

Solubility
Soluble in chloroform. Slightly soluble in methanol.

Notes
Air sensitive. Incompatible with strong oxidizing agents.

Safety and Handling

2°C to 8°C
