The title macrocycle 1 was synthesised in good yield (66%) by a one-pot condensation process from 2,3-bis(chloromethyl)-p-xylene and N,N'-ditosylethylendiamine. The macrocycle was found to undergo isomerization processes at elevated temperature on the NMR time scale (DELTAG(not-equal) 87.8 kJ mol-1) and acts as a suitable host only for toluene. The FAB-MS spectra of 1 is rich, and full of interesting and very diagnostic fragmentation pathways.
