    • Although both routes to C-O bond cleavage (Scheme 2), namely, dehydration - hydrogenation (I - II) and direct hydrogenolysis (III), are empirically referred to as hydrogenolysis, we have used the term hydrogenolysis in its strictest sense, that is, cleavage of the C-O bond accompanied by the addition of hydrogen. Thus, only path III involves hydrogenolysis, while routes I followed by II and route III are collectively referred to as C-O bond scission paths.

    • The term deuteration implies the addition of deuterium to a C=C double bond and not H - D exchange.

    • 5OD, the first distillation step was omitted. When the deuteration of 1-indanol was conducted in cyclohexane, the reaction mixture (consisting of perhydroindane, perhydro-1-indanol and cyclohexane) was passed over a silica gel column to remove the alcohol product. The remaining perhydroindane solution in cyclohexane was concentrated by distilling off excess cyclohexane. This solution was then used directly in NMR analyses. Again, in the case of deuteration of indane in cyclohexane the silica gel step was omitted. In some cases the sample was concentrated further by removing some of the cyclohexane by azeotropic distillation with benzene (b.p. ≈ 77 °C).

    • There is a possibility of extraction of mineral acids (which are frequently used to activate carbon) from the carbon support into the solvent during the reaction. However, measurements of pH of the extracts indicated that the amount of mineral acid present on the carbon support and extracted, if at all, is negligible.
