Uses
Tosyl azide is used for the introduction of azide and diazo functional groups. It is also used as a nitrene source and as a substrate for [3+2] cycloaddition reactions.
Preparation
Tosyl azide can be prepared by the reaction of tosyl chloride with sodium azide in aqueous acetone.
Safety
Tosyl Azide is one of the more stable azide compounds but is still regarded as a potential explosive and should be carefully stored.
