## Abstract The barriers to internal rotation about the CN bond in several thiopiperidides have been determined by the NMR technique. It was found that the barrier height (Δ__G__^‡^) increases in the series cinnamoylthiopiperididem‐and __p__‐substituted cinnamoylthiopiperidides the barriers were s
