The Pd 0 /Au I mediated [C 1 +C 2 ] cross‐coupling reactions of [W(≡CBr)(CO) 2 (Tp*)] (Tp*=hydrotris(dimethylpyrazolyl)borate) and trimethylsilylethynyl‐substituted arenes afford new polycyclic aromatic hydrocarbon propargylidynes [W(≡CC≡CR)(CO) 2 (Tp*)] (R=9‐anthracenyl, 1‐pyrenyl). The strategy extends to the first bis(propargylidyne) and bis(pentadiynylidyne) complexes bridged by phenyl or anthracenyl spacers, and to a tetrakis(propargylidyne) connected through a pyrene core.
