Abstract Reaction of Schwartz's reagent [Cp 2 ZrHCl] n (1)(one or two equivalents) with gem- dinitrile compounds of the type X (CN) 2 [X= CMe 2, CBenz 2, P (NiPr 2) 2] gives the corresponding mono-and di-N-zirconated imino complexes selectively. Substitution reactions of the zirconocene metal fragment with electrophiles such as, for example, chlorophosphanes of the type R 2 PCl, acid chlorides RC (O) Cl or the iminium salt [CH 2 ...
