It is a structural analoque of titanocene dichloride but with vanadium(IV) instead of titanium(IV). This compound has one unpaired electron, hence Cp2VCl2 is paramagnetic. Vanadocene dichloride is a suitable precursor for variety of bis(cyclopentadienyl)vanadium(IV) compounds. Reduction of vanadocene dichloride gives vanadocene (C5H5)2V. ==Preparation== Cp2VCl2 was first prepared by Wilkinson and Birmingham via the reaction of NaC5H5 and VCl4 in THF, followed by work up by extraction with chloroform and hydrogen chloride and recrystallization from toluene. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「vanadocene dichloride」の詳細全文を読む スポンサード リンク
