Mechanism of Reduction of Diphenylacetylene by Metallic Lithium

Mechanism of Reduction of Diphenylacetylene by Metallic Lithium

A zero‐order reaction converts cis‐dilithiostilbene (1), formed upon reduction of diphenylacetylene by lithium, into the trans isomer 2. The cis‐monolithiated adduct acts as a catalyst.
