Acid base reaction, where an acidic sulfide compound substitutes a leaving group with an SH | KSH/Ethanol |
Acid base reaction with sulfur. Replaces leaving group with SR'. Inversion of stereochemistry | C6H5SNa/THF or diethyl ether |
Swern oxidation of primary alcohols, turns alcohol into aldehyde | Primary alcohol + 1) (CH3)2S=O, (COCl2), CH2Cl2, heat 2) (CH3CH2)2N |
Oxidation of primary and secondary alcohols to either aldehyde, ketone, or carboxylic acid | Chromic acid derivative/H2SO4,H2O or PDC/PCC/CH2Cl2 |
Esterification. Chlorine is replaced with OR- group | Primary alcohol + nitrobenzyl chloride derivative/pyridine |
Fischer esterification. Alcohol in carboxylic acid is replaced with alcohol reactant OR- group | Alcohol + acetic acid (Carboxylic acid with one R group) / H+ ions, benzene, heat OR H2SO4, heat |
Alcohol is converted to ether. R group is doubled, oxygen in center | 2 alcohols + H+, heat |
Reduction methods. Reduce carboxylic acids, keynotes or aldehydes to alcohols | NaBH4 + methanol OR LiAlH4, diethyl ether, H2O OR H2, Ni, heat OR OsO4 |
Ring opening. MgBR is replaced by RO- group, with nucleophilic R attaching to carbon chain first | Grignard reagents + ethylene oxide (triangular oxygen) + diethyl ether and H3O+ |
