turns the C=O ketone portion into C=CR

LiAlH4, ether / H3O+ (ketones)

turns ketones into hydroxyl groups

LiAlH4, ether / H3O+ (esters)

splits esters into two primary alcohols R1COOR2 becomes R1COH and R2OH

HOCH2CH2OH / H3O+

protects ketone by forming ring around it. released with H3O+

R1NHR2

replaces =O of ketone with =R1NR2

R2CuLi / H3O+ (alkene)

adds R to carbon of previous double bond

H2NNH2 / KOH

converts aldehydes and ketones into alkanes

NaBH4, ether / H3O+

turns ketones and aldehydes into -OH

CrO3, H3O+

forms carboxylic acid from primary alcohols

LiAlH4, THF / H3O+ (CN)

turns CN into NH2

EtMgI / H3O+ (CN)

C=O replaces CN and ethane adds in

NaOH, H2O / H3O+ (CN)

turns CN into a carboxylic acid

SOCl2, benzene / heat (NH2)

turns CONH2 into CN

KMnO4 (alkene)

splits C=C into two carboxylic acids

NBS, Mg

adds MgBr

CO2, H3O+

adds COOH to MgBr

CH3CH2OH / HCl

This O forms with the O on the carboxylic acid to form an ester

SOCl2

Cl replaces the OH of the carboxylic acid

HCl / H2O

breaks an ester into a carboxylic acid and a primary alcohol

NaOH

The Na bonds to the O- (of the previous OH of the carboxylic acid) and a primary alcohol is formed

ROH / HCl

the O of the alcohol forms with the carboxylic OH to form an ester

R2CuLi, ether (acid chloride)

R replaces Cl

R2MgBr (excess), ether / H3O+

C=O becomes C-OH and 2R bond to the C of the previous C=O

HNMe2 / LiAlH�4 (acid chloride)

In an acid chloride, the C=O disappears and the Cl is replaced by HNMe2

H2O (anhydrides)

breaks anhydride into two carboxylic acids

NaOH, H2O / anhydride reactant with OH, carbox

anhydride splits into two carboxylic acids�one of which bonds to the -OH substituent and forms an ester

NaOH, H2O / anhydride reactant with amide

anhydride splits and -COCH adds to the nitrogen

DIBAH, toluene / H3O+

splits a lactone into a chain with an aldehyde on one end and a hydroxyl on the other end
