Treatment of a cyclic ketone with diazomethane is a method for accomplishing a ring-expansion reaction. The reaction involves the initial nucleophilic attack by diazomethane on the carbonyl carbon to form a tetrahedral intermediate. Collapse of this intermediate is accompanied by bond migration and loss of N2. For example, treatment of cyclohexanone with diazomethane yields cycloheptanone. Draw the structure of the organic product(s) of the ring expansion of this compound:
