The reaction between 1,4,7,10-tetraazacyclododecane and 4-toluenesulphonyl chloride in triethylamine/chloroform yields both the disubstituted isomers of bis-(4-toluenesulphonyl)-1,4,7,10-tetraazacyclododecane. This has been confirmed by H-1 NMR and X-ray crystallographic analyses. (C) 2002 Elsevier Science Ltd. All rights reserved.
