Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Chemical Communications (Cambridge, United Kingdom) called Why do silanes reduce electron-rich phosphine oxides faster than electron-poor phosphine oxides?, Author is Kirk, Alicia M.; O’Brien, Christopher J.; Krenske, Elizabeth H., which mentions a compound: 676-96-0, SMILESS is CP(C)(C)=O, Molecular C3H9OP, Computed Properties of C3H9OP.
Organophosphine-mediated reactions that generate P=O-bonded byproducts can be transformed into catalytic processes by reducing the R3P=O byproduct back to PR3in situ with a silane. DFT calculations explain why the most readily reduced phosphine oxides are those incorporating electron-rich (e.g. alkyl) substituents rather than electron-deficient (e.g. aryl) substituents.
Although many compounds look similar to this compound(676-96-0)Computed Properties of C3H9OP, 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.
