Name: 2-Chloro-5-pyridinesulfonyl chloride. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: 2-Chloro-5-pyridinesulfonyl chloride, is researched, Molecular C5H3Cl2NO2S, CAS is 6684-39-5, about An experimental and theoretical dipole moment study of 2-chloropyridine-5-sulfonyl chloride. Author is Lumbroso, H.; Montoneri, E.; Pappalardo, G. C..
Anal. of the dipole moment (2.00 D) of 2-chloropyridine-5-sulfonly chloride in benzene at 30° supported a model in which the C(5)-SCl group is rotated by 40° from the 2-chloro-1-pyridyl group. Such a model, with the S Cl atom close to the 1-azanitrogen atom, can be explained by interplay of 2 conflicting factors, namely sulfonylchloride-arene conjugation and lesser repulsion between 1 of the O atoms and the aza N atom.
There is still a lot of research devoted to this compound(SMILES：ClC1=NC=C(C=C1)[S](=O)(=O)Cl)Name: 2-Chloro-5-pyridinesulfonyl chloride, and with the development of science, more effects of this compound(6684-39-5) can be discovered.
