2,4,6-Triisopropylbenzenesulfonyl azide, 98%, stab. with ca 10% water, Thermo Scientific Chemicals

Description

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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Applications
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 ɑ-diazo ketones than other methods. It is also used for azide transfer to potassium enolates (KHMDS) to form the ɑ-azido derivatives.

Solubility
Insoluble in water.

Notes
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.
