Dynamic NMR studies13 showed that upon deprotonation of 5 to give 8, the calix-wheels move from the previous two alkylbenzylammonium stations to new positions in which aliphatic chains are inside the calix-cavities. Byconsidering the three different aliphatic sites along the axle and the three possible relative orientations of the two calixwheels, this should lead to seven possible translationalisomers.
