YieldReaction ConditionsOperation in experiment
Ca. 42 %Spectr. With methanesulfonic acid In neat (no solvent) at 80 - 100℃; for 18 h; Synthesis of cucurbit[n]urils in methanesulphonic acid using Diethoxymethane(Ethylal)Unsubstituted glycoluril (19.94 g) and methane sulphonic acid (neat, 82 mL) were placed in a reaction flask and heated to 80 °C. Ethylal (35.21 mL) was added in drop-wise and the reaction mixture was then heated to 100 °C (internal temp) for 18 hours. The reaction mixture was cooled and added to acetone (410 ml) to produce a brown powder which was analysed by1H NMR.Approximate Yields b1H NMR (percent of recovered product) cucurbii[5]urii 8percent, cucurbit[6]uri 42percent, cucurbit[7]uril 43percent, cucurbit[8]uril 7percent, cucurbit[9]uril 0percent, cucurbit[10]uril 0percent, cucurbit[ 13uril 0percent.Residual formaldehyde by HPLC method was 34 ppm.

YieldReaction ConditionsOperation in experiment
Ca. 44 %Spectr. With hydrogenchloride In water at 90 - 100℃; for 18 h; Synthesis of cucurbit[n]urils in hydrochloric acid using paraformaldehyde Unsubstituted glycoluril (20 g) and hydrochloric acid (37 percent w/v, 30 mL) were placed in a reaction flask and heated to 90°C. Paraformaldehyde (8.87 g) was added in portion-wise and the reaction mixture was then heated to 100 °C (internal) for 18 hours. The reaction mixture was cooled and added to methanol (150 mL) to produce a beige powder which was analysed by1H NMR.Approximate Yields by1H NMR (percent of recovered product) cucurbit[5]uril 8percent, cucurbit[6]uril 44percent, cucurbit[7]uril 28percent, cucurbit[8]uril 18percent, cucurbit[9]uril 0percent, cucurbit[10]uril 0percent cucurbit[11]uril 0percent.Residual formaldehyde by HPLC method was 682 ppm.
