Abstract
[(η5-C5Me5)Re(NO)(PPh3)(CCCCCCCC)(Ph3P)(ON)Re(η5-C5Me5)] and [(η5-C5Me5)Re(NO)(PPh3)(CCCCCC)-(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)(CCCCH)], or cross-coupling with the corresponding ethynyl complex; unusual spectroscopic and redox properties are described.Keywords
