Abstract

Nuevo procedimiento de preparación de 2-benzotiazol sulfenamidas, que responden a la fórmula general: **Fórmula** en la cual R representa ya sea un átomo de hidrógeno, o un grupo alquilo o nitro, R1 representa bien sea un átomo de hidrógeno, o un grupo alquilo ramificado o no, cicloalquilo, alquilcicloalquilo, cianoalquilo, hidroxialquilo, R2 representa un grupo alquilo ramificado o no, cicloalquilo, alquilcicloalquilo, cianoalquilo, hidroxialquilo, R1 y R2 pueden igualmente ser grupos alquilenos unidos entre sí por un enlace sencillo o un hetero-átomo. Como ejemplos de tales grupos, se pueden citar los ciclos piperidilo, morfolino. Los procedimientos conocidos referentes a la preparación de los compuestos utilizan como materia prima de partida, bien sea el mercaptobenzotiazol o el disulfuro de benzotiazol.
