ABSTRACT:
An improved process for preparing triazacyclo compounds and, in particular, 1,4,7-tritosyl-1,4,7-triazyacyclononane. The process involves reacting a diethylenetriamine triarylsulphonate with a cyclising agent selected from the group consisting of diaryl sulphonates, dialkyl sulphonates, ethylene dibromide, ethylene dichloride and diacetylglycol in the presence of ultrasound.
