Abstract

The reaction of the osmium - antimony cluster Os₃(μ-SbPh₂)(μ-H)(μ₃, η²-C₆H₄)(CO)₉ (1) with the terminal alkynes PhC≡CH and ^tBuC≡CH was presented. The reaction led to products involving C-C bond coupling with the phenylene ligand on the cluster Os₃(μ-SbPh₂)(μ, η²- HC=C(H)Ph)(μ- η⁴-C₆H₄C-(H)CPh)(CO)₇. It was found that cluster 1 was an effective catalyst for the cyclotrimerization of diphenylacetylene to hexaphenylbenzene.
