(I have no idea if I am right in any of this, but I'll keep trying!)
Could you then react with ozone? A double bonded carbon attached to a cyclohexane, react with 1) O3, 2) CH3SCH3 (part 2 came from a list of reagents I have, but the major part is ozone), that double bond to oxygen will cleave, forming an oxygen double bonded to a cyclohexane ring, and an oxygen double bonded to a carbon (so 2 products).
