Application of 4488-22-6, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 4488-22-6, Name is [1,1′-Binaphthalene]-2,2′-diamine, molecular formula is C20H16N2. In a Article£¬once mentioned of 4488-22-6
Synthesis and X-ray structures of new phosphorus-selenium heterocycles with an E-P(Se)-E? (E, E? = N, S, Se) linkage
Refluxing a toluene solution of Woollins’ reagent, WR, with difunctional aromatic substrates (aryldiamines and aryldithiols) leads to a series of novel five- to seven-membered heterocycles 2a-e, 4a, 4b and 6a-c with an E-P(Se)-E? (E, E? = N, S, Se) linkage in 7-98% isolated yields. This method offers a new approach to the library of phosphorus-selenium heterocyclic compounds. All new compounds have been characterized by IR, 1H, 13C, 31P, 77Se NMR, mass spectrometry and elemental analysis or accurate mass measurement. Four representative X-ray structures are reported.
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 4488-22-6 is helpful to your research., Application of 4488-22-6
