Novel reaction of complex salts [(μ-RE)(μ-CO)Fe2(CO)6][HNEt3] (E = S, Se) with Phosphaalkene t-Bu(Me3SiO)C=PSiMe3. Synthesis and spectroscopic and crystallographic characterization of butterfly Fe2EP clusters (μ-RE)[μ-t-Bu(Me3SiO)CHPH]Fe2(CO)6 (E = S, Se)

Reaction of complex salts [(μ-RE)(μ-CC))Fe2(CO)6][HNEt3] (1, E = S, Se) with phosphaalkene t-Bu(Me3SiO)C=PSiMe3 (2) has been found to afford a series of new butterfly-shaped Fe2-EP clusters of type [(μ-RE)[μ-t-Bu(Me3SiO)CHPH]Fe2(CO)6 (3, RE = EtS; 4, n-PrS; 5, n-BuS; 6, t-BuS; 7, PhSe; 8, p-MeC6H4Se) in quite high yields. This type of cluster may exist as three isomers, namely, e(R)e(H), e(R)a(H), and a(R)a(H), which differ in whether the R group and H atom are attached to E and P atoms with an axial or an equatorial bond. Clusters 3-8 have been characterized by elemental analysis and 1H, 31P, and 77Se NMR spectroscopy, as well as for isomers 3e(R)a(H), 6e(R)a(H), 8e(R)e(H), and 8a(R)a(H) by single-crystal X-ray diffraction analyses. In addition, a possible reaction mechanism has been preliminarily suggested.
