Q

limitations of Friedel-Crafts Alkylation

A
  1. Only alkyl halides can be used… 2. not functional when the aromatic ring is substituted by a strong electron-withdrawing group (such as carbonyl) or by a basic amino group that can be protonated… 3. difficult to stop reaction after a single substitution (polyalkylation is favored)… 4. skeletal rearrangement of alkyl carbocation electrophile sometimes occurs during reaction (especially when using a primary alkyl halide)

because they undergo substitution

128

134
Q

A

135
Q

ether nomenclature

A

simple ethers with no functional groups are named by identifying organic substituents and adding word “ether”; if other functional groups are present then the ether part is considered an alkoxy substituent

136
Q

properties of ethers

A

have nearly the same geometry as water: approximately a tetrahedral bond angle and oxygen is sp^3 hybridized; electronegative oxygen gives compound a slight dipole moment so boiling points are often slightly higher than alkane counterparts; relatively stable and unreactive; can react slowly with oxygen in air to give peroxides (compounds with O-O bond)

137
Q

williamson ether synthesis

A

alkoxide ion reacts with a primary alkyl halide to tosylate in an Sn2 reaction; unsymmetrical ethers should be synthesized from reaction between more hindered alkoxide partner and less hindered halide partner; primary halides and tosylates work best because E2 competition can occur with more hindered substrates; reagents: 1. NaH, THF 2. RX

138
Q

alkoxymercuration of alkenes

A

alkene is treated with alcohol in presence of mercuric acetate or (CF3CO2)2Hg, followed by reaction with NaBH4 to yield ether; markovnikov addition of alcohol to alkene; primary/secondary/tertiary alcohols react well but ditertiary ethers cannot be prepared due to steric hindrance; reagents: 1. (CF3CO2)2Hg, alcohol 2. NaBH4

145
Q

A

the alcohol part

146
Q

acidity increases if negative charge of conjugate base

A

can be spread out/delocalized (which is better with electron-withdrawing groups)

147
Q

alcohol acidity increases if additional electronegative atoms are present because

A

they delocalize the negative charge by induction

148
Q

A

have increased acidity

149

alcohols with more electron withdrawing groups

A

have increased acidity

150
Q

alcohols with the more electronegative electron withdrawing group

A

have increased acidity

151
Q

electron withdrawing group on phenol

A

increases ring’s ability to delocalize the negative charge, making the phenol more acidic

152
Q

electron donating group on phenol

A

decreases ring’s ability to delocalize the negative charge, making the phenol less acidic

153
Q

electron withdrawing group is ortho/para to OH group on phenol

A

the phenoxide negative charge is further delocalized in an additional resonance structure, further increasing the phenol’s acidity

154
Q

electron donating by induction

A

alkyl groups

155
Q

electron withdrawing by induction, electron donating by resonance

A

electron donating groups (groups with lone pair of electrons on first atom) and halogens

171
Q

base-catalyzed epoxide opening using -OH, -OR, R2NH, RMgX

A

if a tertiary epoxide carbon is present, nucleophilic attack occurs primarily at the tertiary position in Sn1 manner; if no tertiary epoxide carbon, nucleophile attack occurs at least hindered site (primary) in Sn2 manner

172
Q

ether cleavage using HBr or HI

A

Sn2: if no tertiary, allylic, or benzylic carbons are attached to oxygen, attack occurs at least hindered carbon (methyl, primary, or secondary) [yields methyl/primary/secondary alkyl halide and primary/secondary alcohol]; Sn1: if tertiary, allylic, or benzylic carbons are attached to oxygen, attack occurs at more hindered carbon [yields tertiary/allylic/benzylic alkyl halide and primary/secondary/methyl alcohol]
