In ChemAxon names there appear to be a cluster of cases where suffixes are being used as prefixes
For example:
1-chloro-4-[(4-chlorobenzene)sulfonyl]benzene (ClC1=CC=C(C=C1)S(=O)(=O)C1=CC=C(Cl)C=C1)
There is formally no indication that the benzene and sulfonyl are actually bonded! This should correctly be named:
1-chloro-4-[4-chlorobenzenesulfonyl]benzene (sulfonyl as a suffix)
or 1-chloro-4-[(4-chlorophenyl)sulfonyl]benzene (sulfonyl as a prefix)
or probably ideally using a method which identifies the symmetry of the molecule around the sulfonyl.
Another example is:
2-[(2-chlorobenzene)amido]benzoate ([O-]C(=O)C1=C(NC(=O)C2=C(Cl)C=CC=C2)C=CC=C1)
which should be named 2-[2-chlorobenzamido]benzoate as there is no such prefix as an amido prefix. Amido is only a functional replacement term or suffix.
EDIT: problem is still outstanding in 5.5.0.0. On a completely unrelated note "imidodicarbonimidic diamide" is still uninterpretable in that version despite claims to the contrary in the release notes.
