Nj. Goodwin et al., SYNTHESIS AND REACTIVITY OF THE FERROCENE-DERIVED PHOSPHINE [FE(ETA-C5H5)-(ETA-C5H4CH2P(CH2OH)(2))], Journal of the Chemical Society. Dalton transactions, (22), 1997, pp. 4377-4384
The air-stable compound [Fe(eta-C5H5){eta-C5H4CH2P(CH2OH)(2)}] 1 has b
een prepared by the reaction of [Fe-(eta-C5H5)(eta-C5H4CH2NMe3)]I with
an excess of P(CH2OH)(3). Compound 1 has been used to produce a range
of other new compounds, thus demonstrating its versatility as a start
ing material; the phosphine oxide [Fe(eta-C5H5) {eta-C5H4CH2P(O)(CH2OH
)(2)}] 2, phosphine sulfide [Fe(eta-C5H5){eta-C5H4CH2P(S)(CH2OH)(2)}]
3, and other derivatives [Fe(eta-C5H5){eta-C5H4CH2P(CH2CH2CN)(2)}] 4,
[Fe(eta-C5H5){eta-C5H4CH2P(CH2NEt2)(2)}] 5, [Fe(eta-C5H5){eta-C5H4CH2P
(O)(CH2NEt2)(2)}] 6, [Fe(eta-C5H5){eta-C5H4CH2P(Me)(CH2OH)(2)}]I 7 and
[Fe(eta-C5H5)-{eta-C5H4CH2P(Me)CH2OH}] 8. Crystal structure determina
tions for 1, 3 and 7 are reported and the hydrogen bonding of each str
ucture described.
