I'm having a hard time deciphering it's IUPAC name like I have 4-butanoxy and 3-propanoxy so far, but how do you put it all together with the double-bonded oxygen?

Thank you and really sorry for the trivial question here.

The motif in the center is carbonic acid, hence your compound is a carbonate as for instance dimethyl carbonate. (Perhaps the BOC group is known to you as a protection of amines, too.)

To the left of the acid you have a butyl rest, to the right an ethyl. You sort them alphabetically, and hence name the compound butyl ethyl carbonate, CAS 30714-78-4.

  • $\begingroup$ The CAS name list also allows ethyl butyl carbonate, without the alphabetical sorting. $\endgroup$ Feb 24 at 14:40

  • $\begingroup$ @OscarLanzi Perhaps equally allowed (as on the CAS site itself), true. On the other hand, a methyl and an ethyl group on atom 3 of a pentane - this is (preferred?) as 3-ethyl-3-methyl-pentane. The brief 4-page abstract of the Red Book names MEK as as ethyl methyl ketone, too (page 4, right hand column). $\endgroup$
