Q

PCC (Cl-CrO3-)

A

Weak oxidizer, Cl-CrO3- attaches to alcohol O as LG

17
Q

Swern oxidation

  1. OS(CH3)2, (COCl)2
  2. NEt3
A

18
Q

DMP

A

Weak oxidation, reaction stops at the aldehyde

19
Q

Baeyer-Villiger Oxidation

A

mCPBA, creates an ester and a carboxylic acid

20
Q

Thioacetals

A

Reaction of aldehydes/ketones with thiols/thioacetals

21
Q

Thiols

A

Contains S (like EtSH, or HS–SH)

22
Q

Raney Ni, H

A

Used in ‘desulfurization’ after thioacetal formation to form a carbonyl/CH2

23
Q

Primary amines + ketone/aldehyde, acid

A

Formation of imines

24
Q

Secondary amines + ketone/aldehyde, acid cat

A

Formation of enamines

25
Q

HCN

A

Weak/slow formation of cyanohydrin with ketone/aldehyde

26
Q

NaCN, KCN

A

Strong formation of cyanohydrin with ketone/aldehyde

27
Q

Et2O, R-X and Mg/Li

A

Formation of organometallics, Mg will form RMgX (Grignard reagent) and Li forms LiX and RLi

28
Q

Grignard reagents + epoxides

A

Formation of 2° alcohols with aldehydes and 3° alcohols with ketones

29
Q

TBSCl, ImH, DmF and then TBAF

A

TBSCL protects -OH groups so Grignard reagents can add, then removed by TBAF to leave the OH

30
Q

Phosphorus ylide and aldehyde/ketone

A

Wittig reaction - forms an alkene (Z isomer only)

31
Q

Phosphonate ester and aldehyde/ketone

A

HWE reaction - forms an alkene (E isomer only)

32
Q

E isomer

A

Entgegen form - higher atomic priority on opposite sides of a double bond

33
Q

Z isomer

A

Zusammen form - higher atomic priority on the same side of a double bond
