Li and light : Alkenyl‐substituted lithium cyclopentadienides, which are in equilibrium with the substituted lithocene anion structure 1 , undergo a photochemical [2+2] cycloaddition to yield selectively the carbon–carbon coupling product 2 . This is a rare case of organic functional‐group chemistry for a reactive organolithium compound.
