Descripción

4-Hydroxycoumarin is involved in annulation reactions, due to the relatively high acidity of the C-H bond at the 3-position: a three-component reaction with isocyanides and dialkyl acetylene dicarboxylates affords annulated 4H-pyrans.

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 4-hidroxicumarina participa en reacciones de anulación, debido a la acidez relativamente alta del enlace C-H en la 3-posición: una reacción de tres componentes con isocianuros y dicarboxilatos de acetileno de dialquilo proporciona 4H-piranos anulados.

Solubilidad
Soluble en etanol y dimetilformamida. Insoluble en agua.

Notas
Almacenar en un lugar fresco. Mantenga el recipiente bien cerrado en un lugar seco y bien ventilado. Incompatible con agentes oxidantes fuertes y bases fuertes.
