Are ethyl iodophenylundecylate and Ethyl-10-(Iodophenylundecanoate) the same compound?
The &quot;structures&quot; you are trying to post and their respective names do not match, as I cannot spot a phenyl group in there. (Also it is hard to tell from this diagram.) But based on what you gave us, I believe these are the same compounds, where ethyl 10-(4-iodophenyl)undecanoate is the correct IUPAC name and Ethyl iodophenylundecylate is a shortened synonym. I also found trivial names for this compound, for example Pantopaque and Iofendylate.
You can access this molecules record on ChemSpider and you will find a couple more names attached to it. From the same page is the following structure taken:
