Abstract
Un procedimiento para la preparación de sales de diazonio en posición 3 del pirazol, de la fórmula-01 (I): **(Fórmula-01)** en donde X es un radical -CO- COO-, n es 0 o 1, R es H (en cuyo caso n es siempre = O), un alquilo normal o ramificado de C1-C4, un radical aromático o heterocíclico, asímismo substituido, en particular un radical fenílico con la estructura de la fórmula-02: **(Fórmula-02)** en donde m puede variar entre 0 y 3, y los sustituyentes R3 iguales o distintos entre sí para m mayor que 1, son alquilos lineales o ramificados de C1-C4, halógenos, grupos ciano, nitro, sulfónico, carboxílico, carboxiésteres con una cadena lineal o ramificada de C1-C4, alcoxiloscon una cadena lineal o ramificada de C1-C4, grupos de trifluorometilo, grupos de acilamino con una cadena alifática lineal o ramificada de C1-C4, o grupos de sulfonamida del tipo de fórmula-03: **(Fórmula-03)** en donde los sustituyentes R4 y R5, iguales o distintos entre sí, son hidrógeno o cadenas alifáticas lineales o ramificadas de C1-C4; R1 y R2 iguales o distintos entre sí, son hidrógeno, cadenas lineales o ramificadas de C1-C4, o radicales bencénicos sustituidos o insubstituidos; caracterizado porque se someten a diazoación oxidativa 3-amino-pirazolinas de la estructura de la fórmula-04: **(Formula-04)** en donde X, n, R, R1, R2 tienen el significado antes indicado en conexión con las sales de diazonio de estructura.
