Abstract

En un nuevo procedimiento para la oxidación de un alcohol primario y/o secundario, se emplea un agente oxidante en presencia de un di-terc-alquilnitroxilo, en un medio de reacción acuoso a un pH por debajo de 7. El di-terc-alquilnitroxilo es en especiaI4-hidroxi-TEMPO y el proceso se lleva a cabo en particular para la oxidación de carbohidratos tal como almidón.
