2‐Lithiobicyclo[2.1.1]hexene, prepared from bicyclo[2.1.1]hexan‐2‐one , is the key intermediate in an efficient synthesis of interesting bicyclo[2.1.1]hexane derivative such as 1–3 . Noteworthy is the reactivity of 3 , which acts more as a 2π‐electron than as a 4π‐electron system toward olefins such as tetracyanoethylene. Furthermore, the new compounds have unusual 13 C NMR spectra.
