By double mercury‐lithium exchange using tert ‐butyllithium, it has been possible for the first time to prepare both cis ‐ and trans ‐1,2‐dilithioethylene. Both compounds are unstable and lose lithium hydride; however, the cis compound reacts more rapidly than the trans compound. The title compounds were identified by reaction with dimethyl sulfate.
