Reaction of unsymmetrical thioalkynes RCCSC2H5, RCH3, C6H5, with iron and ruthenium carbonyls. How to build a polynuclear compound using the CS cleavage
thioalkynes couple via the triplebond according to a classical reaction type. However, the alkyne asymmetry yields three types of coupling which were all observed. (2) The particular role of sulfur is displayed first by the cleavage of one or the other carbon-sulfur bond, or more seldomly both of them simultaneously, and second by the well known ability of sulfur to ligate metal. (3) The combination of

A di-μ3-carbyne cluster [Fe3(CO)9μ3-CN(CH3)2}(μ3-CC2H5)] has been synthesized by reaction of [Fe2(CO)9] with the alkynylethyl sulphide C2H5SCCCH3 and trimethylamine oxide at 69°C. One of the μ3-carbyne functions resulted from the rare activation of the three CH bonds of a trimethylamine methyl group.
