Proton magnetic resonance studies of specifically deuterated cyclohexane compounds: Part III. Long‐range couplings (⁴JHH) in cyclohexane

This is the authors' abstract. We don't add key points for this paper.

The preparation of 1,1,3‐triprotoperdeuterocyclohexane is reported. The low‐temperature PMR spectrum of this compound shows a superposition of two 3‐spin systems, originating from the two chair conformations. A long‐range coupling constant between the equatorial protons at positions 1 and 3 of 1.7 Hz is derived. The coupling between the 3‐axial proton and the 1‐protons is smaller than 0.4 Hz.
