Cyclopentadienyl iron dicarbonyl styrene chalcogenosulfonates: synthesis and structure of CpFe(CO)2SeSO2CH=CHPh

Abstract

In this contribution, we report the preparation of iron thiosulfonato complex CpFe(CO) 2 SSO 2 CH=CHPh (1) and its selenosulfonato analogue CpFe(CO) 2 SeSO 2 CH=CHPh (2) featuring styrene moiety. 1 and 2 are obtained by electrophilic attack of (l-E x )[CpFe(CO) 2 ] 2 (E = S; x = 2-4, E = Se; x = 1) on the sulfur atom of styrene sulfonyl chloride ClSO 2 CH=CHPh. The new compounds, 1 and 2 have been characterized by elemental analyses, IR, 1 H-, 13 C{ 1 H}-NMR, UV-Vis spectroscopy and the structure of 2 is determined by X-ray crystallography.
