To which ring are you referring?  A diagram may help.

I am not aware of a name for this reaction (like a Finkelstein reaction, for example).  It is just the conversion of an ether into an iodoalkane, as far as I know.

Its the cleavage of an ether by strong acids. Only HBr and HI can do this trick.

Iodotrimethylsilane can also do an analogous reaction.
