Abstract The complexes CpFe(CO) 2 SiBr 3 , CpFe(CO) 2 SiI 3 , CpFe(CO) 2 SiBr 2 (OMe), and CpFe(CO) 2 SiI(NH-cyclo-C 6 H 11 ) 2 are prepared by the reaction of CpFe(CO) 2 SiR 3 (R = OMe, NH-cyclo-C 6 H 11 ) with HBr, HI and CH 3 I. Treating CpFe(CO) 2 SiCl 3 with a large excess of NaN 3 , KOCN or KSCN yields the first tri-pseudohalogensilyl—transition-metal-complexes. The compounds are characterized by IR and mass spectra. A new method of preparation of the already known complex CpFe(CO) 2 SiH 3 is described starting from CpFe(CO) 2 SiCl 3 and LiAlH 4 .
