WebISOLUTE® Si-TsOH (SCX-3)is the bound equivalent of p-toluene sulfonic acid with a pKa <1. Similar to ISOLUTE propylsulfonic acid (SCX-2)1, it can be used to (a) scavenge amines and other bases such as anilines and borohydrides (b) as an acid catalyst in reac-tions or (c) as a replacement for aqueous or organic acids in quenching reactions. Web2. The oxonium ion liberates a hydrogen ion that is picked up by the oxygen anion in an acid‐base reaction. Small amounts of acids and bases catalyze this reaction. This occurs because the addition of acid causes a protonation of the oxygen of the carbonyl group, leading to the formation of a full positive charge on the carbonyl carbon ...
