abstract

  • [(η5-C5Me5)Re(NO)(PPh 3)(C≡CC≡CC≡CC≡C)(Ph3P)(ON) Re(η5-C5Me5)] and [(η5- C5Me5)Re(NO)(PPh3)(C≡CC≡CC≡C) -(Ph3P)(ON)Re(η5-C5Me5)], which contain the longest chains of elemental carbon tethered between two transition metals to date, are prepared by Cu(OAc)2 coupling of [(η5-C5Me5)Re(NO)(PPh3) (C≡CC≡CH)], or cross-coupling with the corresponding ethynyl complex; unusual spectroscopic and redox properties are described.
