The supersilylated tetrasulfane tBu3Si-S4-SitBu3: Synthesis, structure, and its reaction behavior towards [Fe(CO)5]

The tetrasulfane tBu3Si-S4-SitBu3 was formed in high yield when S2Cl2 was treated with two equivalents of Na(thf)2SSitBu3 in thf. X-ray quality crystals of the tetrasulfane tBu3Si-S4-SitBu3 (monoclinic space group P21/c) were grown from a benzene solution at ambient temperature. UV-induced degradation of [Fe(CO)5] in the presence of the tetrasulfane tBu3Si-S4-SitBu3 led to the formation of the carbonyliron complex [Fe4(μ4−S)2(CO)11].
