Hydrogenolysis of (M(CH3)2) (M=Zr, Hf) bonds gives new racemic and optically active substituted zirconocene and hafnocene dihydrides A: (RCp)2MH2 (M=Zr, Hf; R=Me, Me2CH, Me3C, PhCH2) and B: (R*Cp)2MH2 (M=Zr, Hf; R*=MeCHEtCH2, PhCHEtCH2), R*CpCpHfH2 (R*=PhCHCH3).Substitution of hydridic hydrogens by halogens, mobile hydrogen compounds, addition with unsaturated derivatives are studied.The A and B type complexes are good catalysts in hydrogenation of alkenes; the B type complexes give only poor asymmetric induction in catalytic reduction of prochiral alkenes.
