Kine c Product = ?

Thermodynamic Product = ? - -Kine c product is the one that forms at the fastest rate (from
lowest energy transi on state, look at carboca on)

-Thermodynamic product is the most stable final product (look at subs tu on around double
bond)



Diels Alder Reac on

-reagent?

-accelerated by ___ on diene and ___ on dienophile

-endo or exo? - -heat

-accelerated by EDG on diene and EWG on dienophile

-in bicyclic products, always get the endo product where bridge points away from the
subs tuents



EDG or EWG?

a) -NR C=O R2

b) -CN

c) -NR1R2

d) -NO2

e) Br - a) EDG

b) EWG

c) EDG

d) EWG

, e) EWG but directs ortho, para



What effect does it have on ortho, meta, para posi ons?

-Electron dona ng group

-Electron withdrawing group - -EDG: slight nega ve on ortho, para (direct electrophiles ortho,
para)

-EWG: slight posi ve on ortho, para (direct meta)



Huckel's criteria for Aroma c Compounds (4) - 1. Cyclic

2. Have one p-orbital on each ring atom

3. planar

4. Have 4n + 2 electrons in p-orbitals where n is a whole number



Cl2, FeCl3

Br2, FeBr3 - Add Cl or Br to aroma c ring (Chlorina on or Bromina on)

(Mechanism: Cl+, FeCl4-, electrophilic addi on, byproducts: HCl, FeCl3)



HNO3, H2SO4 - Add NO2 to aroma c ring (Nitra on)

(Mechanism: NO2+, electrophilic addi on)



SO3, H2SO4 - Add SO3H to aroma c ring (Sulfona on)



R C=O Cl

AlCl3 - Friedel Cra<s Acyla on



RCl
