REACTIONS BETWEEN Ce(Ⅳ) COMPLEXES AND SUBSTITUTED CYCLOPENTADIENYL ALKALI METAL DERIVATIVES(Ⅱ) ——REACTION OF (HP(C_2H_5)_3)_2CeCl_6 AND C_5Me_5Li
《Chinese Science Bulletin》1987年第1期28-30,共3页沈琪 周朋 
Study on the chemical properties of Ce （Ⅳ） complexes has been quite limited so far. We have first reported that Ce （Ⅳ） is reduced completely to Ce （Ⅲ） when （C5H6N）2CeCl6 reacts with C5Me5Li. In order to und...
