Recommanded Product: 4-Acetamidobenzoic acid, Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, causing turnover rates to depend strongly on interfacial structure and composition. 556-08-1, Name is 4-Acetamidobenzoic acid, SMILES is CC(=O)NC1=CC=C(C=C1)C(O)=O, belongs to phthalazine compound. In a article, author is Ongoma, Peter O., introduce new discover of the category.
A kinetic study of aqua substitution in dinuclear Pt(II) complexes, [{cis-Pt(OH2)(NH3)(2)}(2)-mu-pmn](ClO4)(2) (pmn), [{cis-Pt(OH2)(NH3)(2)}(2)-mu-pdn](ClO4)(2) (pdn), [{cis-Pt(OH2)(NH3)(2)}(2)-mu-qzn](ClO4)(2) (qzn), [{cis-Pt(OH2)(NH3)(2)}(2)-mu-pht](ClO4)(2) (pht) and [{cis-Pt(OH2)(NH3)(2)}(2)-mu-pzn](ClO4)(2) (pzn) (pmn = pyrimidine, pdn = pyridazine, qzn = quinazoline, pht = phthalazine, pzn = pyrazine) by different sulphur-donor nucleophiles, thiourea (TU), N,N-dimethylthiourea (DMTU) and N,N,N,N-tetramethylthiourea (TMTU) was carried out. The reactions were followed under pseudo-first-order conditions as a function of nucleophile concentration and temperature using stopped-flow and UV-Vis spectrophotometric methods. The reactivity of the nucleophiles follows the order TU > DMTU > TMTU. The general order of reactivity for the aqua complexes follows pzn > qzn > pmn > pdn > pht which is confirmed by the obtained pK (a) values and the quantum chemical calculated NBO charges at the metal centre. The negative values reported for the activation entropy confirm the associative nature of the substitution process. The results demonstrate the strong connection between structural and electronic characteristics of the diazine-bridging ligand and reactivity of the dinuclear Pt(II) complexes.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 556-08-1, in my other articles.
