Étude des Paramètres de Résonance Magnétique Nucléaire et de la Stéréochimie de Thiono‐2 R‐2 Dithiaphosphorinanes‐1,3,2

Abstract

The ' € I , "C and "P n.m.r. spectra of eleven 2-R-2-thiono-1,3,2-dithiaphosphorinanes with various R groups attached to the phosphorus atom have been recorded and analysed. In the compounds where R=CI, OMe or N, the molecule adopts a chair conformation with the R group axially oriented. When
