The complete mechanism for iodination of 2, 6-dimethylcyclohexanone under basic conditions is to be drawn and the major product is to be predicted. Concept introduction: Any α hydrogens present in a carbonyl compound are weakly acidic and can be extracted by a strong base like hydroxide. This converts the electrophilic α carbon into a strongly nucleophilic species that can be used in a nucleophilic substitution reaction. As a strong nucleophile, this carbanion favors S N 2 reactions. In an S N 2 reaction, the nucleophile attacks the electrophilic carbon in the substrate, displacing the leaving group on it in a single-step, concerted reaction. Since the nucleophile attacks first, it must approach the electrophilic carbon from the direction opposite to the leaving group. This generally results in a single product with an inverted symmetry at the reaction center.
