Reaction of (η5-C5Me5)Re(NO)(PPh3)(C⋮CH) and Cu(OAc)2 (1.5 equiv, 80 °C, pyridine) gives the orange-brown ReC4Re complex (η5-C5Me5)Re(NO)(PPh3)(C⋮CC⋮C)(Ph3P)(ON)Re(η5-C5Me5) (2, 88%) as a 50:50 diastereomer mixture. Crystallization affords

One major objective has been the preparation of compounds in which sp carbon chains span two metals, L{sub n}M(C){sub x}M`L`{sub n`} (I). There are now many examples of such C{sub 2} complexes. However, higher homologs remain much less well explored.
