10,13‐Bis( p ‐tolyl­sulfonyl)‐1,4,7‐tri­thia‐10,13‐di­aza­cyclo­penta­decane

The title compound, C 24 H 34 N 2 O 4 S 5 , is the di­tosyl­ated precursor to the mixed aza–thia macrocycle 1,4,7‐tri­thia‐10,13‐di­aza­cyclo­penta­decane ([15]­aneN 2 S 3 ) and is prepared by reacting bis(2‐mercaptoethyl) sulfide with O,O ′, N,N ′‐tetra­tosyl‐ N,N ′‐bis(2‐oxy­ethyl)­ethyl­endi­amine in di­methyl­form­amide in the presence of Cs 2 CO 3 . Molecules lie across crystallographic twofold axes. The macrocyclic framework adopts a [] conformation and the two tolyl­sulfonyl groups are directed away from the ring cavity. There is extensive disorder of the methyl­ene groups of the macrocyclic backbone.
