Abstract

Some novel tetrayne complexes RC₂[Co₂(CO)₄dppm]CCCCC₂[Co₂(CO)₄dppm]R (5) (where R = SiMe₃, a; 4-MeC₆H₄, b; C₆H₅, c; 4-MeOC₆H₄, d; 4-FC₆H₄, e; dppm = 1,2-bis(diphenylphosphino)methane) have been synthesized either by oxidative coupling of RC₂[Co₂(CO)₄dppm]CCH (4) or by lithiation and subsequent hydrolysis of RC₂[Co₂(CO)₄dppm]CH CHCl (8). An X-ray structure determination of 5a reveals that the two Co₂(CO)₄dppm units are trans to each other. The cobalt units can be removed from 5 by oxidizing reagents.
