From 13 C‐7 labeled toluene the following 13 C‐methyl o ‐ and p ‐substituted toluenes were synthesized: o ‐NO 2 , ‐NH 2 , ‐I and CN; p ‐NO 2 and ‐NH 2 . Each of these labeled compounds was studied by carbon magnetic resonance to determine all carbon‐13carbon‐13 splittings involving the methyl carbon.
