The aldols formed in aldol additions can be easily dehydrated to yield conjugated enals (enones)

If a chiral atom attached to the carbonyl group, the stereoselectivity of nucleophilic addition follows the Cram’s rule

The most characteristic reaction of aldehydes and ketones is nucleophilic addition to the carbon-oxygen double bond

Many other pairs of reagents that form cabocations (orcarbocationlike species) may be used as well

No addition of bromine No oxidation No hydroation Slow addition at high temperature and pressure

The reactivity of organometallic compounds increases with the percent ionic character of the carbon-metal bond. RLi and RMgX are of great importance in organic synthesis

Acid-Catalyzed hydration of Alkenes Oxymercuration-Demeruration Hydroboration-Oxidation

Alcohols are compounds whose molecules have a hydroxyl group attached to a saturated carbon atom
