Popis:	1. The electronic influence of substituent s in compounds RSO2Hal on the change in the frequency of the S=O bond in the IR spectra, the NQR of Cl35, and the basicity of the sulfuryl oxygen atom was considered. 2. The sulfur atoms in compounds with a sulfuryl group played the role of a “buffer” — an electron acceptor, as a result of which p-π -conjugation of the substituents has little effect on the polarity of the S=O and S-Cl bonds and prevents nucleophilic attack.
