## Abstract A series of 7‐^13^C‐labeled __o__‐substituted toluene derivatives and carboxyl‐^13^C‐isocrotonic and crotonic acid were synthesized and studied by ^13^C NMR spectroscopy to obtain ^13^C^13^C spin‐spin coupling constants involving the labeled carbon. The __cis__ ^3^__J__(CC) values were
