What is ChemSpider?
There seems to be some confusion regarding the naming of aromatic amines. When there is no locant for the substituent it is located on the nitrogen - not the ring! Thus dimethyl-o-toluidine is N,N-dimethyl-o-toluidine or 2,N,N-trimethylaniline. There is something wrong with the name-to-structure algorithm
Thank you for the feedback - It could we be that these structures are based on an imperfect name-to-structure conversion. I've deleted the synonyms that seem to be in error.
