摘要：

The reaction of [Cp*MCl4] (M = Nb, Ta; Cp* = C5Me5) with PH2R in toluene at room temperature gives the primary phosphine complexes [CP*MCl4(PH2R)] [Cp* = C5Me5; M = Nb: R = Bu-t(1a), Ad (2a), Cy (3a), Ph (4a), 2,4,6-Me3C6H2 (Mes) (5a); M = Ta: R = Bu-t(1b), Ad (2b), Cy (3b), Ph (4b), Mes (5b)] in high yield. 1-5 were characterized spectroscopically (NMR, IR, MS) and by crystal structure determinations. The starting material [Cp*TaCl4] is monomeric in the solid state, as shown by crystal structure determination.
