IUPAC names accidentally differing in hyphen only

Here is an example of two compounds



> 
> $$\ce{CH3CH2COOCH3}$$
>  *vs*
>  $$\ce{(CH3)2CHCOO-}$$
> 
> 
> 


i.e.

whose possible IUPAC names



> 
> methyl propanoate  
> 
> *vs*  
> 
>  methylpropanoate

accidentally differ only in presence/absence of a space. (Note that complete, unambiguous name of the second compound is 2-methylpropanoate)


Is there an (accidental) example of two IUPAC names for different compounds, that differ only in presence/absence of a **hyphen** ("-") instead?


(Question might sound hypothetical, strange and inappropriate, but is related to to [this one](https://chemistry.stackexchange.com/questions/74049/hyphenation-of-chemical-names))


**UPDATE**: Mentioned ‘methylpropanoate’ preferred IUPAC name is 2-methylpropanoate. There's a better example pair:


* phenyl acetate ($\ce{CH3COOPh}$)
* phenylacetate ($\ce{PhCH2COO^{-}}$)


Note that in some language localized official IUPAC nomenclatures, the names really differ by the hyphen instead of the space (e.g. in Czech: fenyl-acetát vs fenylacetát), but I was wondering about the English nomenclature.




The compound with the formula $\ce{CH3COOPh}$ is known as phenyl acetate, but the IUPAC name is: phenyl ethanoate.


The compound $\ce{PhCH2COO-}$ has the IUPAC name: 2-phenylethanoate.


The similarity is interesting, but the names are distinct enough, unless I'm missing something.
