Abstract
UN PROCEDIMIENTO PARA LA DESHIDROGENACION DE AMIDAS A NITRILOS QUE CONSISTE EN QUE LA DESHIDROGENACION SE LLEVA A CABO EN PRESENCIA DE UN ADUCTO A PARTIR DE TRIOXIDO DE AZUFRE Y UNA AMINA COMO REACTIVOS DE DESHIDROGENACION EN UN MEDIO BASICO. LA AMINA DEL REACTIVO DE DESHIDROGENACION ES EN PARTICULAR UNA AMINA TERCIARIA, COMO UNA AMINA ALIFATICA, P. E. UNA TRIALQUILAMINA O UN COMPUESTO HETEROAROMATICO QUE LLEVA NITROGENO, P. E. PIRIDINA O UN DERIVADO DE PIRIDINA. DE ESTA MANERA SE DESHIDROGENAN POR EJEMPLO AMIDAS ALIFATICAS, AROMATICAS Y HETEROAROMATICAS PARA OBTENER LOS CORRESPONDIENTES NITRILOS, COMO POR EJEMPLO 5CARBAMOIL-4-METIL-OXAZOL PARA OBTENER 5-CIANO-4-METIL-OXAZOL, UN VALIOSO PRODUCTO INTERMEDIO EN LA SINTESIS DE LA PIRIDOXINA.
