New Planar π‐Systems, II 1) . ‐ On the Preparation and Structure of Tetrakis(phenylethynyl)ethene The preparation of tetrakis(phenylethynyl)ethene ( 1 b ) has been repeated. Among various routes to this highly unsaturated cross‐conjugated π‐system, the dimerization of bromide 2 via the carbene 3 is the most simple one. Full spectroscopic data for 1 b are reported for the first time, as is its X‐ray structural analysis at ‐ 95°C.
