SNN′-substituted diimidosulphur compounds from alkylation or arylation of diimidosulphur compounds: a simple method for quantitative determination of Grignard, lithiumalkyl and lithiumaryl reagents

Abstract

S-alkyl- or aryl-substituted NN′-dialkyl-or diaryldiimidosulphur compounds are obtained in the reactions of R¹MgX, R¹₂Mg and R¹Li with R²–NSN–R²(R¹ and R²= alkyl or aryl); the reactions are quantitative and can be used in titrations of solutions of these reagents.
