We have investigated the rotation barriers of 4-carbamoylphenanthrene and 4-thiocarbamoylphenanthrene and the asymmetric transformations of the novel 4-carboxy-5-carbamoylphenanthrenes. The similar ArC and CN barriers of 92 kJ/mol of 4-carbamoylphenanthrene indicate a strongly correlated process o...
