“…It is to be notecl that coupling constants in three-membered ,uld four-membered rings (3,10,20) do not agree very well with those expected from Icarplus' work, in contrast to the situation 1\-11ich exists in most five-ant1 six-lnelnbered rings.…”

A B S T R A C T T h e proton ~~u c l e a r magnetic resonance (N.M.R.) spectra o f the four diastereoisomers o f camphane-2,3-diol are reported. T h e coupling constants between the 2-, 3-, and 4-protons agree with t h e values predicted byICarplus for ethane derivatives. In particular, the cis (0" dihedral angle) coupling constants (7.7 and 8.9 c.p.s.) INTRODUCTIONIndirect spin-spin coupli~lg constants in substituted ethane clerivatives have attracted attention because of the depeizcleilce of their values on the dihedral angle between the CH bonds involved (1-7). The dilzedl-a1 angles are 60" and 180" in non-cyclic substiti~tecl ethanes, ~vhich, in general, exist in staggered rather than eclipsed forms. Tlzese are also the dihedral angles between vicinal C H bonds in six-membered rings existing in chair conforinations. I n each case the observed coupling constants may be weighted averages if more than one conformation exists to a n appreciable extent.Karplus (8) '~lfaaltz~script received iVovenrber 28, 1960.

“…Electrochemical hydrogen titration [19,20] was carried out in an undivided O 2 free cell, with special tightly cavities for the electrodes and the Hamilton syringe containing the organic substrate. The electrolytic solution and the headspace were flushed with Ar during 10 minutes, so that the gas pressure was close to 1 atm.…”
