## Abstract Carbon‐13 NMR spectral data for a series of symmetrical 2,6‐disubstituted adamantanes (O, CH~2~, CH~3~, OH, OCOCH~3~) are presented. The substituent effects on ^13^C chemical shifts are additive, except for carbons 2 and 6 in 2,6‐adamantanedione. The non‐additivity of the substituent

✦ Synopsis
Abstract
Carbon‐13 chemical shifts of fourteen para‐substituted benzylbenzenes have been determined. The relative substituent chemical shifts (SCS) of the methylene carbons and the aromatic ring carbons (C‐4, C‐1′ and C‐4′) correlated well with the Hammett substituent effects using the dual substituent parameter method. The transmission of substituent effects through the benzylbenzene system is briefly discussed.
