New families of coordinated carbon: oxidative coupling and cross-coupling of a transition metal butadiynyl complex to bimetallic M–C[triple bond, length half m-dash]CC[triple bond, length half m-dash]CC[triple bond, length half m-dash]CC[triple bond, length half m-dash]C–M and M–C[triple bond, length half m-dash]CC[triple bond, length half m-dash]CC[triple bond, length half m-dash]C–M adducts

Abstract

[(η5-C5Me5)Re(NO)(PPh3)(C[triple bond, length half m-dash]CC[triple bond, length half m-dash]CC[triple bond, length half m-dash]CC[triple bond, length half m-dash]C)(Ph3P)(ON)Re(η5-C5Me5)] and [(η5-C5Me5)Re(NO)(PPh3)(C[triple bond, length half m-dash]CC[triple bond, length half m-dash]CC[triple bond, length half m-dash]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[triple bond, length half m-dash]CC[triple bond, length half m-dash]CH)], or cross-coupling with the corresponding ethynyl complex; unusual spectroscopic and redox properties are described.
