2. Provide a mechanism for the following remarkable transformation. Use arrows to show the flow of electrons and indicate all formal charges. Note that the rate of this reaction is several thousand times faster than the rate of substitution of hydroxide ion on 3-chloropentane under similar conditions. HINT: The first step of the mechanism is an intramolecular Sn2 reaction in which a ring forms, and the second step involves a subsequent intermolecular Sn2 reaction in which hydroxide ion is the...
