The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 2-Chloropyridine 1-oxide( cas:2402-95-1 ) is researched.Recommanded Product: 2-Chloropyridine 1-oxide.Scott, Paul T.; Kauffman, Jim W.; Rogers, J. W.; Williams, R. J. published the article 《Stability constants of stannous chloride-pyridine N-oxide complexes in acetonitrile》 about this compound( cas:2402-95-1 ) in Journal of Inorganic and Nuclear Chemistry. Keywords: stability tin complex pyridine oxide; IR pyridine oxide tin complex; chloropyridine oxide tin complex stability; picoline oxide tin complex stability; substituent effect stability tin complex. Let’s learn more about this compound (cas:2402-95-1).
Stability constants were determined for 8 Me- and Cl-substituted pyridine N-oxide adducts of SnCl2 in MeCN solution The complexes had a 1:1 stoichiometry in the concentration ranges studied. An IR spectrophotometric method was used to determine concentrations of the equilibrium species from the N-O stretching band of the free ligand from mass balance relations. The equilibrium concentrations were such that the N-O stretching bond of the complexed ligand also appeared in most of the spectra shifted to lower frequencies by 50-75 cm-1. The stability constants of the complexes were rationalized in terms of electronic and steric effects of the substituents on the pyridine N-oxide ring.
