Dipole moments and conformation of thiosulphinates
Abstract
The conformation of some S-alkyl and -aryl thiosulphinates has been evaluated from the electric dipole moments measured in benzene solution. The synclinal conformation (A) here observed is the same as for sulphinates. From comparison with disulphides and their S-oxides, it appears that the stereochemistry of all these compounds is controlled by the gauche interaction of the two C–S bonds.
