Search for evidence, in the Cambridge Structural Database, that the cyclic bromonium ion actually does exist.

•	Start ConQuest and hit the Draw button to open the Draw window.

•	Sketch the cyclic bromonium ion shown below. Remember to specify a charge of +1 on the bromine. This can be done, e.g. by right-clicking on the Br atom at selecting Charge, followed by Positive and then +1 from the resulting pull-down menus.

 

•	Hit Search, then in the Search Setup window hit Start Search.

•	As soon as you start the search, the ConQuest interface moves to the View Results pane. After a few moments, the refcodes of any hit structures will appear in the list on the right-hand side.

•	You should retrieve two hits (refcodes DAKVUG and WEVPIW). Both are examples of adamantylidene-adamantane-bromonium ions. Examine these two structures.

•	We can now confirm that bromonium ions are indeed real.
