With a sufficiently bulky ancillary ligand (L = Tp∗) the aryl bromide is ammenable to cross-coupling reactions that enable more elaborate derivatives to be prepared. These including symmetric bis(alkylidynyl)anthracenes as well as non-palindromic examples bearing disparate metals and/or co-ligands. In contrast, these couplings fail for smaller ligands (L = Tp, Tm) where it was found that Pd0 or Pt0 were instead able to coordinate across two WC bonds to give trimetallic bow-tie complexes, [W2M{μ-CC(C6H4)2CBr}2(CO)4(L)2] (M = Pd, Pt; L = Tp, Tm).We gratefully acknowledge the Australian Research Council (DP190100723 and DP200101222) for funding.application/pdfen-AUThis journal is © The Royal Society of Chemistry 2021Symmetric and non-symmetric anthracen-diylis(alkylidynes)202110.1039/d1dt02537f2022-11-13
