7-bromoisatin was treated with excess PhMgBr to afford tertiary alcohol 9 in 96 % yield. Isatin oxime triflates undergo a facile fragmentation which is promoted by DBU, to form anthranilonitriles after hydrolytic work-up.

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.

Aplicaciones
La 7-bromoisatina se trató con exceso de PhMgBr para producir el alcohol terciario 9 con un 96 % de rendimiento. Los triflatos de oxima de isatina se someten a una fragmentación facil que se facilita mediante DBU para formar antranilonitrilos después del trabajo hidrolítico.

Solubilidad
Ligeramente soluble.

Notas
Almacenar en un lugar fresco. Mantener el recipiente bien cerrado en un lugar seco y bien ventilado. Almacenar lejos de los agentes oxidantes fuertes.
