WebThe nucleophile cannot squeeze in between the alkyl groups of a 3° substrate to attack the backside of the α carbon. The effect is even worse if the nucleophile itself is bulky. However, a nucleophile like tert-butoxide ion is also a strong base. Therefore, it will go for a β hydrogen in an E2 attack. WebAlso, a strong hinderedbase such as tert-butoxide can be used. The bulkiness of tert-butoxide makes it difficult for the oxygen to reach the carbon (in other words, to act as a nucleophile). It is more likely to pluck off a proton, which is much more accessible than the electrophilic carbon). WebExploiting retro oxa-Michael chemistry in polymers†. Karin Ratzenböck ab, Johanna M.
