Abstract
The reaction of LiBu
n
with [(mes)
2
P(H)![[double bond, length as m-dash]](https://www.rsc.org/images/entities/char_e001.gif)
O]
affords the diorganophosphinate complex
[(mes)
2
P(O)
2
Li·2thf] 1 and
[(mes)
2
PLi], however, addition of
[Cd{N(SiMe
3
)
2
}
2
] to the mixture
gives the diorganophosphinite complex [{Me
3
-
Si)
2
N}Cd{(mes)
2
PO}
2
Li·2thf] 2; the formation of these complexes illustrates that
the ligand functionality of 1 can be controlled by the character of the
coordinated metal ion.
