The diamide exo, exo ‐ β ‐P 4 S 3 (NHCH(Me)Ph) 2 has been made in solution using enantiomerically pure or racemic PhCH(Me)NH 2 , and its three diastereomers characterised by complete analysis of their 31 P{ 1 H} NMR spectra.The unsymmetric diastereomer contains phosphorus atoms, made chemically non‐equivalent by the chirality of the substituents, which show a large 2 J (P—P—P) coupling to each other (225.2 Hz).
