Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 6298-19-7, Name is 2-Chloropyridin-3-amine, molecular formula is , belongs to pyridine-derivatives compound. In a document, author is Yang, Yu-Chen, Name: 2-Chloropyridin-3-amine.
Regioselective conversions of H(4)pdta (1,2-propanediaminetetraacetic acid) and H(4)eed3a to their triacetates on peroxotitanates
1,2-Propanediaminetetraacetic acid (H(4)pdta = C11H18O8N2) is degraded selectively to 1-methyl-1,2-propanediaminetriacetic acid (H(3)pd3a = C9H16O6N2) with a yield of 75% at room temperature, while N-(2-hydroxyethyl) ethylenediaminetriacetic acid (H(4)eed3a = C10H18O7N2) is converted with difficulty to ethylenediaminetriacetic acid (H(3)ed3a = C8H14O6N2) on peroxotitanates(iv), showing the influence of the uncoordinated leaving group. Various species in the reaction sequence are isolated and fully characterized, including (NH4)[Ti(O-2)(Hpdta)]H2O (1), (NH4)(3)[Ti(O-2)(pdta)H(pdta)(O-2)Ti]7H(2)O (2), (NH4)[Ti(O-2)(pd3a)]H2O (3) and (NH4)[Ti(O-2)(Heed3a)]H2O (5). Peroxo dimer 2 forms a strong intramolecular hydrogen bond [2.451(3) angstrom] as an intermediate in the peroxo Ti-pdta system, which results in the absence of a fully deprotonated species of peroxo pdta titanate. A catalytic reaction of the peroxo titanate (NH4)(3)[Ti(O-2)(pdta)H(pdta)(O-2)Ti]7H(2)O (2) for the conversion of pyridine to pyridine N-oxide shows 94% conversion at 80 degrees C.
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 6298-19-7, in my other articles.
