    • The product ratio in the UV experiment (6/4 61:39 after 2.3 h) is slightly lower than the product ratio found in the NMR experiment (6/4 68:32 after 40 h). This is due to the longer reaction time for the NMR experiment relative to the UV experiment. The non-4-OT-catalyzed background dehydration reaction therefore contributes more significantly to formation of 6 during the NMR experiment than during the UV experiment. There is hardly any non-4-OT-catalyzed background retro-aldol reaction (see Table 1).
