摘要：

Whereas [(Me3Si)2P]2PH 1 by BuLi is attacked at the PH group to give [(Me3Si)2P]2PLi 2, the related chromium carbonyl complex (Me3Si)21PIV-2PIV(H)-3PIII(Si-Me3)2 . Cr(CO)4 3 with BuLi yields Li(Me3Si)1PIV-2PIV(H)-3PIII(SiMe3)2 . Cr(CO)4 4 by cleaving a Si-P bond at the chromium substituted 1P atom. Dissolved in ether, 4 is stable for a longer time, while under comparable conditions 2 forms Li3P7 which is not obtained from 4. MeOH in 3 cleaves selectively the Me3Si groups from the complex substituted P atom yielding (Me3Si)(H)1PIV-2PIV(H)-3PIII(SiMe3)2 . Cr(CO)4 5 and H21PIV-2PIV(H)-3PIII(SiMe3)2Cr(CO)4 6. 5 and 6 seem to be stable in contrast to the uncoordinated triphosphanes which are not known.
