Synthesis and 1 H NMR Spectrum of a Tetramethylated 1,2,4,5‐Tetraaza‐3,6‐diphosphacyclohexane Derivative The reaction of phenoxythiophosphoryl dichloride with 1,2‐dimethylhydrazine yields the new 1,2,4,5‐tetraaza‐3,6‐diphosphacyclohexane derivative 2 . The 1 H NMR spectrum of the N‐methyl groups can be interpreted as an AX 6 A′X′ 6 spin system. The coupling constants 3 J (PH), 4 J (PH), and 3 J (PP) are derived from a calculated spectrum.
