Chemistry, like all the natural sciences, begins with the direct observation of nature¡ª in this case, of matter.51805-45-9, Name is 3,3′,3”-Phosphinetriyltripropanoic acid hydrochloride, SMILES is Cl[H].OC(=O)CCP(CCC(O)=O)CCC(O)=O, belongs to chiral-phosphine-ligands compound. In a document, author is Fener, Benjamin E., introduce the new discover, Name: 3,3′,3”-Phosphinetriyltripropanoic acid hydrochloride.
Sterically Encumbered 2,3-Dihydrophosphindole and Its Chalcogenides
Reduction of 2-benzyl-1-mesityl-5,7-dimethyl-2,3-dihydrophosphindole 1-oxide (2-O), which was prepared by catalytic addition of dimesitylphosphane oxide across phenylacetylene via dimesityl-phenylethenylphosphane oxide (1), with excess of trichlorosilane in toluene yielded 2-benzyl-1-mesityl-5,7-dimethyl-2,3-dihydrophosphindole (2). Straightforward oxidation of 2 with sulfur and selenium in toluene at 110 degrees C allowed the isolation of crystalline colorless 2-benzyl-1-mesityl-5,7-dimethyl-2,3-dihydrophosphindole 1-sulfide (2-S) and 1-selenide (2-Se). The hindered rotation of the P-bound mesityl group around the P-C bond is indicative of significant intramolecular steric strain. Despite this strain, the P-E bond lengths (E = S, Se) lie in expected ranges.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 51805-45-9 is helpful to your research. Name: 3,3′,3”-Phosphinetriyltripropanoic acid hydrochloride.
