The assignments of the 13 C NMR signals of 2‐(bromomethyl)naphthalene (1) were derived by comparison of its spectrum with those of the α,α‐D 2 and 1‐D derivatives, by determination of relative spin‐lattice relaxation rates and by inspection of the 13 C, 1 H spin coupling patterns. Literature assignments of 1 and of 2‐(bromomethyl)‐6‐methylnaphthalene are corrected. The procedure by which these assignments has been obtained is critically evaluated. Very good additivity of substituent effects on chemical shifts is observed in the 13 C NMR spectra of 2,6‐ and 2,7‐bis(bromomethyl)naphthalene.
