An Experimental and Theoretical Dipole Moment Study of 2-Chloropyridine-5-sulphonyl Chloride
Abstract Analysis of the dipole moment of 2-chloropyridine-5-sulphonyl chloride in benzene at 30 °C (2.00 D) supports a model in which the C(5)-SCl group is rotated by 40° from the 2-chloro-1-pyridyl group (see Figure 1). Such a model, with the S-Cl chlorine atom close to the 1-azani-trogen atom, may be explained by interplay of two con-flicting factors, namely sulphonylchloride-arene conjuga-tion and lesser repulsion between one of the oxygen atoms and the aza-nitrogen atom.
