To prepare the cyclic product other than six-membered rings from intramolecular aldol addition of 2,6-heptanedione Concept introduction: Aldol reaction is an addition reaction of aldehydes and ketones . Aldol reaction is a reversible reaction and occurs in the presence of a strong base like sodium hydroxide. One molecule (aldehyde or ketone) acts a nucleophile and attacks the electrophilic carbon center of the other molecule to give the addition product. The product is named β -hydroxy aldehyde if two aldehydes combine and β -hydroxy ketone if two ketones combine. If a compound has two functional groups that can react with each other, an intramolecular reaction readily occurs if the reaction leads to occur five or six-membered rings.

A. B. b. Now consider the two bicyclic molecules A. and B. Note that A. is a dianion and B. is a neutral molecule. One of these molecules is a highly reactive compound first characterized in frozen noble gas matrices, that self-reacts rapidly at temperatures above liquid nitrogen temperature. The other compound was isolated at room temperature in the early 1960s, and is a stable ligand used in organometallic chemistry. Which molecule is the more stable molecule, and why?
