Reference of Trimethylphosphineoxide. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: Trimethylphosphineoxide, is researched, Molecular C3H9OP, CAS is 676-96-0, about Phosphonium Phenolate Zwitterion vs. Phosphonium Ylide: Synthesis, Characterization and Reactivity Study of a Trimethylphosphonium Phenolate Zwitterion. Author is Xiao, Jing; Li, Qiang; Shen, Ruwei; Shimada, Shigeru; Han, Li-Biao.
4-Methoxy-3-(trimethylphosphonio)phenolate was obtained from a regioselective addition of PMe3 to p-quinone monoacetal. This compound undergoes hydrogen isotope exchange with D2O or CD3CN, and is capable of catalyzing H/D exchange of CD3CN with substrates bearing weakly acidic hydrogens. It exhibits similar reactivity to phosphorus ylides for olefinations of aldehydes. A possible tautomerization between the phosphonium phenolate zwitterion and phosphonium ylide is proposed for the first time to rationalize the unique reactivity.
Although many compounds look similar to this compound(676-96-0)Reference of Trimethylphosphineoxide, numerous studies have shown that this compound(SMILES:CP(C)(C)=O), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
