Reactions of K2[Fe(CO)3(PPh3)]: Reductive Sb-Sb coupling with Ph2SbCl to form trans-[Fe(CO) 3(PPh3)(Sb2Ph4)] and salt metathesis with Me3SbCl2 to yield trans-[Fe(CO)3(PPh 3)(SbMe3)]

In contrast to the ferrate K2[Fe(CO)4], the phosphane-substituted ferrate K2[Fe(CO)3(PPh3)] (1) reacts with the stibane derivative Ph2SbCl by metal-assisted reductive Sb-Sb coupling to give the distibane complex trans-[Fe(CO) 3(PPh3)-(Sb2Ph4)] (3). The distibane ligand in 3 is terminally η1-coordinated trans to the phosphane ligand. However, the stiborane derivative Me3SbCl2 reacts with 1 in a metathetical substitution reaction to form the monostibane complex trans-[Fe(CO)3(PPh3)(SbMe3)] (5). Both compounds have been characterized by spectroscopic (IR, NMR, MS), analytical (C, H) and X-ray diffraction analyses. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005.
