double bond to carbonyl

primary alc + PCC

aldehyde

primary alc + H2CrO4

carboxylic acid

acid cl derivatives

anhydride, thiester, ester, amide

anhydride derivatives

thioester, ester, amide

thioester can become what derivtaive

ester, amide

ester can become what derivatives

amide

amide

no conversion “blank can become what derivative”

what derivatives can use a)LiAlH4, b)H+ and what do they become

they become alcohols

Acid Cl

Anhydride

Thioesetr

Ester

No amide

TMSCl or TIPSCl

add TMS or TIPS to one of the OH's

TBAF

brings back the OH molecule that has TMS or TIPS connected to it
