WebCHEM3412 Lab Ambident Nucleophiles. SN2 reaction is a type of nucleophilic substitution, where a nucleophile attacks an electrophile and expels a leaving group. To minimize the side reactions, a good leaving group on an unhindered carbon and a strong nucleophile are required. The strongest nucleophiles have a negative charge and it is ... WebThe most common ambident nucleophiles are enolate ions. Attacks from those varieties of nucleophiles can regularly bring about the formation of multiple products.
