[en] Using the method of IR spectroscopy it has been ascertained that in the systems sulphenyl chloride-lithium perchlorate metal cation is coordinated not with nucleophilic part of sulphenyl chloride but with its electrophilic fragment. Coordination by lithium cation of electron-donor centres of sulphenyl chloride derivatives is also confirmed by the results of quantum-chemical calculations

[en] The NMR method has been used to study the effect of sobstitute electronic properties in reagents on stereoisomerism in arylsulfenchlorides addition to β-deuterostyrenes under the conditions excluding mutual transformation of stereoisomers (kinetic control). Easy transformation of stereoisomers under the conditions usually used for carrying out electpophilic addition reactions is traced. Aryl sulfenchloris des addition to the sUbstituted Z- and epsilon-β - deuterostyrenes, irrespective of the type of the substitutes in the benzene ring of both reagents+ proceeds trans-stereospecifically
