Thiophosphoryl compounds as novel inducing agents in the iodine–azide reaction

Abstract

The application of organophosphorus compounds as inducing agents in the iodine–azide reaction was investigated. The induction activity was exhibited by thiophosphoryl compounds; their induction coefficients were dependent on the number and nature of sulphur atoms in the P(S)_n function. These relationships can be used for the group differentiation of organophosphorus compounds, for example phosphates, thiophosphates and dithiophosphates. On the basis of their induction activity the microdetermination of thiophosphoryl inductors on a nmol scale was elucidated.
