• Five new SiNSi bridged metallocene dichloride complexes of the type [CpSiMe 2N(R)SiMe 2Cp]MCl 2 (Cp=C 5H 4, C 9H 6; R=alkyl, M=Ti, Zr, Hf) were synthesized using a new type of amine elimination reaction. All complexes were characterized by 1H-, 13C-, 15N- and 29Si-NMR spectroscopy. An X-ray structure analysis was performed for complex [C 5H 4SiMe 2N( n Bu)SiMe 2C 5H 4]HfCl 2 ( 4)
