WebApr 19, 2004 · Aprotic polar solvents such as DMF, acetonitrile or DMSO can be protonated to form stable triflate salts when treated with triflic acid. The reaction of the same solvents with N,N-bis(trifluoromethanesulfonyl)imide led to the isolation of the corresponding N,N-bis(trifluoromethanesulfonyl)imide salts. WebHence, aprotic solvents boost reaction rates of a S N 2 reaction. Had a protic solvent been used instead of an aprotic solvent, the reaction would not have proceeded or proceeded very slowly because protic solvent molecules will participate in hydrogen bonding with the nucleophile and prevent the nucleophile from attacking the substrate.
