Abstract

Un procedimiento para la preparación de compuestos de N- tritilimidazol de fórmula: **(Fórmula I)** donde R1, R2 y R3 son independientemente un átomo de hidrógeno, un grupo alquilo o un grupo fenilo; X1, X2 y X3 son independientemente un grupo alquilo o un radical electronegativo y n1, n2 y n3 son cada uno de ellos un número entero igual a 0, 1 ó 2; cuyo procedimiento consiste en hacer reaccionar un derivado de tritilcarbinol de fórmula: **(Fórmula II)** donde X1, X2, X3, n1, n2 y n3 son los definidos anteriormente, con un derivado de tri(1-imidazolil)fosfina de fórmula: **(Fórmula III)** en un disolvente adecuado, a una temperatura comprendida entre -5º y 130ºC.
