If given two hexane rings linked to a S in the middle, what would the IUPAC name be?
1 Answer
The preferred IUPAC name is (cyclohexylsulfanyl)cyclohexane.
Explanation:
The structural formula of your compound is
The IUPAC has five acceptable ways of naming thioethers.
Method 1. Substitutive nomenclature
We prefix the name of the substituent group
This method gives the preferred IUPAC name: (cyclohexylsulfanyl)cyclohexane.
Method 2. Functional class nomenclature
We put the names of the alkyl groups before the functional class name of "sulfide."
The name of the compound becomes dicyclohexyl sulfide.
The IUPAC uses three other methods to name more complicated molecules. I mention them here only for the sake of completeness.
Method 3, Multiplicative nomenclature
The name would be 1,1'-sulfanediyldicyclohexane.
Method 4. Skeletal replacement nomenclature
The
The name becomes dicyclohexylthiamethane.
Method 5. Phane nomenclature
We cannot apply phane nomenclature to this simple compound.
