Cyclization reactions,such as the Dieckmann condensation,are best carried out using fairly dilute solutions of the compound to be cyclized.Why is this so? September 21, 2022 by 8i9x6 It then is possible to use less base. The reagents generally are expensive. A smaller amount of the compound to be cyclized can be used. Intermolecular condensation is minimized at low concentration. The concentration factor is unimportant. See Answer Intermolecular condensation is minimized at low concentration.
