WebFeb 11, 2024 · 1. You need to protonate the oxygen in order to actívate the molecule towards nucleophilic attack by the nitrogen of Ethyl amine. pH plays a very important rule here. Too low pH gives an efficient protonation of the oxygen, but it also protonates the nitrogen of the Ethylamine (As ethylamine is weak base due to the lone pair of electrons on ... WebSo let's show the results of our acid-base mechanism. So on the left, right, the lone pair on the left of the oxygen didn't do anything. The lone pair on the right of the oxygen picked up a proton, formed a bond, and so we get this with a plus one formal charge on the oxygen.
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.
