Why do tertiary amines react with quaternary ammonium ions?
- Because a tertiary amine is a relatively poor leav- ing group, the reaction requires heat. the leaving group is a tertiary amine CH 3 CH CH 2 HO NCH 3 H 2 O CH 3 CH 3 CH 3 CH 2 CH 2 NCH 3 ++ CH 3 CH 3 + quaternary ammonium ion

What is the leaving group of a tertiary amine?
- Because a tertiary amine is a relatively poor leav- ing group, the reaction requires heat. the leaving group is a tertiary amine CH 3 CH CH 2 HO NCH 3
Do tertiary alcohols work well with S N 2 reactions?
- This reaction works well only with tertiary alcohols because there is no competing S N 2 reaction. CH 3 CH 2 C CH 3 CH 3 OH CH 3 CH 2 C CH 3 CH 3 OTsC H 3 CH CCH 3 + + CH 3 OH CH 3 ? OTs TsCl pyridine CH 3 O Cl an E2 reaction Biological Dehydrations Dehydration reactions occur in cells.
