Structure and intramolecular mobility of N-(phosphoryl)-or N-(thiophosphoryl)amides and -thioamides: VIII. Structure of N-(thiophosphoryl)-S-organylbenzimidothioates by NMR spectroscopy

Abstract

N-(Diisopropoxythiophosphoryl)-and N-(diisopropoxyphosphoryl)-S-organylbenzimidothioates, which contain one and two imidothiol fragments, are structurally homogeneous in solutions. Cis arrangement of the Ph and P(X)(OPr-i)2 substituents about the C=N bond (E isomer) was deduced from the 3JPNCC constants.
