Abstract

Compuestos de la fórmula 1) que estén cuaternizados con radicales alquilicos se emplean preferentemente como agentes de alquilación sulfatos de dialquilo (como el sulfato de dimetilo y el de dietilo), haluros de alquilo (como el cloruro de metilo, el yoduro o bromuro de tilo, de propilo y de butilo, el cloruro o bromuro de alilo y el cloruro o bromuro de crotilo) o sulfonatos de alquilbenceno (como el sulfonato de p-metilbenceno, etilbenceno o clorobenceno). Si se desea preparar compuestos de la fórmula 1) que estén cuaternizados con un radical bencílico, se emplean preferentemente para la bencilación hauros de bencilo, como el clouro de bencilo Otro agentes de cuaternización son por ejemplo, BrCH 2CH 2 OH, BRCH 2CHOHCH 3, derivados de ácido haloacético como CLCH 2CO 2CH 3, BRCH 2COOH, BRCH 2COOCH 3 , ClCH 2CN, ClCH 2CONH 2, ClCH 2COHCH 3 y ClCH 2CON(CH 3) 2, lo mismo que óxido de etileno u óxido de propileno en presencia de aniones apropiados, como,por ejemplo, del ácido fórmico, acético o láctico.
