Through addition of (μ-alkylthio)(μ-halomagnesiumthio)hexacarbonyldiiron, (μ-RS)(ν-XMgS)Fe_2(CO)_6,to α,β-unsaturated esters or nitrile, followed by alcoholysis of the intermediates in situ, eighteen β-func-tionally substituted iron-sulfur clusters (μ-RS)(μ-ZCH_2CH_2S)Fe_2(CO)_6 have been synthesized in high yields.The structures and conformers of thirteen new complexes have been confirmed by C/H analysis and thedata of IR and ~1H NMR. This method, compared with a known Michael reaction procedure, has threeadvantages: starting materials are cheaper and easily available; manipulation is simple and yields of thecomplexes are quite high.
