Abstract
A series of 4-substituted-1,2-diethylnylbenzenes were prepared (1a–f) and subjected to Bergman cyclization. Bulk cyclization proceeded to produce the corresponding 2-substituted naphthalenes (2a–f) in good yields (59–78%). Kinetic experiments show a linear free energy relationship between the cyclization rate and the Hammett σm substituent coefficient and the Swain–Lupton field and resonance parameters.
