Lewis-Acid-Induced Transformation of a Terminal Carbonyl Ligand: Synthesis and Structure of the Alkyne-Cluster-Analogue [(μ-H)3Os3(CO)9{μ3,η2-C(OBC8H14)B(Cl)}]
The alkyne‐complex analogue 2 is formed on electrophilic attack of 9‐Cl‐9‐BBN at the BCO moiety of 1. By reaction of 2 with BCl3 the cluster 3 is accessible; hence, 2 can be regarded as a model of the intermediate which has been postulated for the direct reaction of 1 with BCl3 to give 3.
