LECTURE In the case of hydration, we found out that the unhappy the carbonyl function, the more reactive it is, and therefore the hydration equilibrium will lie to the right. Reactivity also increases. If you have stabilized carbonyls like ketones, reactions are slower and equilibria are more balanced. Then we moved onto alcohols and acetals, and then onto amines. Because of the nitrogen, there is the possibility of obtaining the imine, which can be isolated. For secondary imines, water eliminates to the carbon side. 4. Addition of Non-organometallic carbon nucleophiles a. Cyanide makes cyanohydrins Mechanism: Usefulness: C-C bond formation with –CN as a versatile functional group. b. The Wittig Reaction Phosphonium salt synthesis The charge on P acidifies the adjacent C-H: deprotonation gives a so-called ylide.
