Abstract

The first example of the group V metallocene dihalides substituted in the cyclopentadienyl rings with electron-withdrawing substituents is reported. This study includes synthesis and spectroscopic characterization of the series of vanadocene and niobocene compounds functionalized in the cyclopentadienyl rings with the ester groups. Structures of (η5- C5H4COOPh) 2VCl2,(η5-C5H4COOMe) 2VBr2· CH2Cl2,(η5-C5H4COOPh) 2NbCl2,(η5- ...
