Abstract

Abstract Kinetics of nucleophilic additions of butylamine to phenylsulfonyl isothiocyanate was investigated by the stopped-flow UV spectroscopic method and the transfer of electronic effects of substituents on the reaction centre through the SO 2 group was examined. The structure and the polar character of SO 2 NCS, NCS and SO 2 groups is discussed.
