X-ray Crystallographic and NMR Spectroscopic Study of (η2-Alkene)(μ-alkyne)pentacarbonyldicobalt Complexes: Arrested Pauson−Khand Reaction Intermediates
Abstract
The hexacarbonyldicobalt complexes of a range of 5-alkynyl-5H-dibenzo[a,d]cycloheptenes, 11a−e, readily undergo loss of a carbonyl ligand with concomitant formation of pentacarbonyldicobalt clusters, 12a−e, in which the vacant coordination site on cobalt is now occupied by the C(10)−C(11) double bond of the central seven-membered ring. These (η2-alkene)(μ-alkyne)pentacarbonyldicobalt complexes provide structural models of the first step of the …
