Abstract

Esta invención se refiere a una sal de sulfonio, incluyendo su procedimiento de fabricación, que se utiliza eficazmente como iniciador fotoácido o radical fotoiniciador durante la polimerización y un generador fotoácido, dejando los grupos protectores de compuestos orgánicos, especialmente como un generador fotoácido útil del fotoresistor amplificado químicamente que se emplea en materiales semiconductores. Ya que la sal de sulfonio de esta invención, preparada mediante una reacción en una sola etapa entre un compuesto sulfóxido y un compuesto aromático en presencia de anhídrido perfluoralcanosulfónico, tiene las ventajas de superar algunos de los defectos de la técnica anterior para preparar la sal de sulfonio mediante dos etapas utilizando el reactivo de Grinard, esta invención puede proporcionar una nueva sal de sulfonio con mayor rendimiento que no se puede alcanzar en la técnica anterior y también incluso preparar cualquier sal convencional de sulfonio con mejor rendimiento.
