Reduction of phenyl silyl acetylenes with lithium led to the unexpected formation of a dilithium dibenzopentalenide derivative together with the expected 1,4‐dilithio‐1,3‐butadiene. The bulkiness of the silyl substituent of the phenyl silyl acetylene strongly affects its reduction mode. Further details may be found in the Communication by M. Saito and co‐workers on page 1504 ff.
