Abstract

A mild and efficient method for the mono–oxidation of diols to the corresponding hydroxyaldehydes with trialkylammonium fluorochromates(VI), R3NH[CrO3F] (R= CH3, C2H5 C3H7 and C4H9), in solution at room temperature, and in solution under microwave radiation, is reported. The easy procedure, simple work–up, short reaction times, and excellent yields are advantages of these reagents.

Keywords: Trialkylammonium fluorochromates(VI); oxidants; oxidation; diols; microwave; room temperature.

 

Resumen

Se describe un método eficiente y suave para la mono–oxidación de dioles a los hidroxialdehidos correspondientes con fluorocromatos(VI) de trialquilamonio, R3NH[CrO3F] (R = CH3, C2H5, C3H7 y C4H9), en solución a temperatura ambiente y en solución bajo irradiación de microondas. La facilidad del procedimiento y la sencillez de la extracción del producto, así como de los tiempos de reacción cortos y los rendimientos elevados, son una muestra de las ventajas de estos reactivos.

Palabras clave: Fluorocromatos(VI) de trialquilamonio; oxidantes; oxidación; dioles; microondas; temperatura ambiente.
