Studies on ¹³C Magnetic Resonance Spectroscopy. X. ¹³C Nuclear Magnetic Resonance Chemical Shifts of 2-Substituted Naphthalenes and Their 6-Methoxy Derivatives

Abstract

^<13>C chemical shifts of 2-substituted naphthalenes and their 6-methoxy derivatives were determined by the aids of the additivity of the substituent effect and the selective H-D exchange reaction. The reliability of the additivity of the shielding parameters of monosubstituted benzenes for the above naphthalene series were acknowledged, and the linear relations between the chemical shifts and shielding parameters or substituent constants were confirmed.
