Draw all possible substitution products for this reaction with pseudoephedrine:
Only the right is possible through SN2...
What mechanism(s) can lead to this possible product?
SN1 only: see retention of stereocenter
Which of these bases are considered too "bulky" to undergo substitution reactions?
DBU and Hunig's Base
Draw all possible elimination products for this reaction with pseudoephedrine:
Cannot proceed through E2...
What predominant mechanism can lead to this product?
E2 (E1 will lead to same product but unlikely to occur)
What molecular structures stabilize carbocations for unimolecular reaction mechanisms?
Predict the product and what mechanism:
Undergoes SN2
What mechanism does this reaction proceed by?
SN1
