Tosyl azide is a reagent used in organic synthesis.[1]
Uses
Tosyl azide is used for the introduction of azide and diazo functional groups.[1] It is also used as a nitrene source and as a substrate for [3+2] cycloaddition reactions.[1]
Preparation
Tosyl azide can be prepared by the reaction of tosyl chloride with sodium azide in aqueous acetone.[2]
Safety
Tosyl Azide is one of the more stable azide compounds but is still regarded as a potential explosive and should be carefully stored.
