Transition-Metal Silyl Complexes, 27. - Silyl-Substituted Heteromultinuclear Complexes by Reaction of the Anionic Silyl Complexes - and - with Dihalides of Zinc, Cadmium, or Mercury

The anionic silyl complexes - (1) and - (4) react with equimolar amounts of ZnCl2, CdCl2, or HgBr2 to give the dinuclear complexes MeCpMn(CO)2(SiMePh2)MX (2; MX = ZnCl, CdCl, or HgBr) or Fe(CO)3(PPh3)(SiR3)MX (5; MX = CdCl or HgBr); the Fe-Zn complex is unstable.Reaction of 2 and 5 with a second equivalent of 1 or 4 yields the symmetrical trinuclear complexes 2M (3; M = Cd, Hg) and 2Hg (6) or the unsymmetrical trinuclear complex MeCp(CO)2(Ph2MeSi)Mn-Hg-Fe(CO)3(PPh3)(SiR3) (7).The symmetrical complexes containing Mn-Zn-Mn or Fe-Cd-Fe units are not formed, presumably for steric reasons.With an excess of mercury halides 3 (M = Hg) and 6 react by silyl halide elimination. - Keywords: Heteromultinuclear Fe and Mn complexes with Zn, Cd, Hg/ Transition-metal silyl complexes
