The NMR variable temperature behaviour of a series of N-aryl-N-benzyl alkyl carbamates was investigated.The barrier to rotation about the N-aryl bond was determined for all the compounds studied.The values obtained, which are in good agreement with those found for structurally related N-aryl-N-benzylamides, are in the range ΔG=60.7-89.6 kJ mol-1.For some carbamates another conformational phenomenon has been observed, namely the hindered rotation about the carbonyl carbon-nitrogen bond, with a barrier to rotation corresponding to reported values for similar systems.
