Ether substitution

WebThis is an example of a very general type of reaction, called a nucleophilic substitution re- action, or nucleophilic displacement reaction. In the simplest type of nucleophilic substitu-tion reaction, a Lewis base, acting as a nucleophile, donates an electron pair to an electrophile to displace a leaving group. (You should review these terms in Sec. 3.4B if … WebNotes: The third example could also be written “H 3 O+” . Note that excess HI will convert primary alcohols to alkyl halides via SN2, but not phenol (C 6 H 5 OH) since sp 2 hybridized carbons do not undergo S N 1 or S N 2 reactions.. Mechanism: Strong acid (HI) protonates the ether oxygen, which turns it into a better leaving group (Step 1, arrows A and B). …
