Aplicaciones

2,4,6-Triisopropylbenzenesulfonyl azide is used as a reagent for diazo transfer to ketones, e.g. under phase-transfer conditions, giving better yields of sterically-hindered ?-diazo ketones than other methods. It is also used for azide transfer to potassium enolates (KHMDS) to form the ?-azido derivatives.

Notas

Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Recommended storage temperature is 2 - 8°C.
