Complex-Chemical Synthesis of Cyclic 1.2-Dithiolato Ligands with the nido Cluster [(CO)3,FeS]2. — Molecular Structure and Partial S-Oxidation of Hexacarbonyl(μ2,-cis-1,2-cyclohexanedithiolato-S,S)diiron
The cyclic alkenes, dienes, and trienes C6H10, C8C14, C5H6, C8C12 and C7H8 are inserted into the S-S bond of the nido cluster [(CO)3FeS]2 (1) by photochemically induced [2+2] cycloaddition reactions to give the complexes 2–6; thus, saturated and unsaturated cyclic 1,2-dithiolato ligands can be selectively built onto the complex in a μ2-bridging fashion. According to an X-ray structure analysis, the μ2-1,2-cyclohexanedithiolato-S,S complex 2a with the pseudotetrahedral skeleton [(CO)3FeS]2 crystallizes in the monoclinic space group P21/c; the S2 moiety is bridged by cyclohexane with 1,2-cis configuration. As an example, the partial S oxidation of 2a was carried out, leading to 2b by selective transformation of one thiolato into a sulfenato function.
