Abstract

Treating the complexes [Hg{C≡CC≡W-(CO)₂L} ₂] (L = HB(pz)₃ (1a), HB(pz′)₃ (1b);pz = pyrazol-1-yl; pz′ = 3,5-dimethylpyrazol-1-yl) with 1 equiv of cis-[PtCl₂(PPh₃)₂] or a catalytic amount of trans-[RhCl(CO)-(PPh₃)₂] provides the bimetallic complexes [L(CO)₂-W≡CC≡CC≡CC≡W(CO) ₂L] (L = HB(pz)₃ (2a), HB(pz′)₃ (2b)), the first examples of dimetallaoctatetra-1,3,5,7-ynes. Catalytic amounts of [RhCl(CO)(PPh₃)₂] also provide 2a and 2b in good yields.
