✦ Synopsis

Abstract

The barrier to internal rotation in a series of p‐substituted nitrosobenzenes has been determined by means of variable temperature ^13^C NMR. Substituent (X) effects on the barrier are similar to those observed for acetophenones and benzaldehydes. In addition, dimerization of the nitrosobenzenes was observed at low temperature for X = CH~3~, CI and H. The barrier height is discussed in terms of contributions from resonance effects.
