A full account of a useful transformation from silylated 1,4‐dilithio‐1,3‐butadienes to α‐lithio siloles is described. These lithio siloles formed by this procedure are general, in terms of substitution patterns and synthetic methods, affording diversified silole derivatives. Notably, some structurally complex molecules, such as bridged bis‐silole compounds, have been synthesized easily and successfully
